In equipments with separate bypass line, a galvanic iso-
lation transformer has to be installed in any of both UPS
input power supplies (rectifier input or static bypass), in
order to avoid the direct connection of both lines through
the internal wiring of the equipment.
This is only applicable,when both power supply lines
come from different electrical networks, for example:

4.3. Operating principle.
This manual describes the installation and operating of the Un-
interruptible Power Supply (UPS) from SLC TWIN RT series,
as equipments that can work as a single units or connected in
parallel with a maximum of two units (equipments higher than 3
kVA only).
UPS from SLC TWIN RT series assures a maximum protection
of any critical load, keeping the power supply voltage to the loads
between the stated parameters, with no break, when a failure,
fluctuation or deterioration happen in the electrical commercial
mains and with wide range of available models (from 0,7 kVA to
10 kVA) and allow adapting the model to the end-user needs.
Thanks to the used technology, PWM (pulse width modulation)
and the double conversion, the UPSs from SLC TWIN RT series
are compact, cold, silent and with high efficiency.
The double converter principle cancels any perturbation of the
energy mains fluctuations. A rectifier converts the AC alternating
current from mains into DC direct current, which keeps both the
optimal battery charge level and supplies the inverter that at the
same time generates a sinewave AC alternating voltage ready
to supply the loads permanently. In case of input mains power
supply fault, the batteries supply clean energy to the inverter.
The design and UPS construction from SLC TWIN RT series
have been done in accordance with the international standards.
In models up to 3 kVA, there are available IEC outlets associated
to configure groups by means of the control -LS1 and LS2-. At
higher power models available automatic protections per each
outlet group and also they have terminals to make the corre-
sponding power connection.
The complete series has connectors for USB and RS232 ports
and EPO too for an external installation by the end-user of a an
emergency button, as an option. In the models from 0,7 to 3 kVA
it is supplied a dry contact to install a remote start up and shut-
down of the equipment (Dry-in), as well as an auxiliary contact as
an alarm (Dry-out).
As an option, inside the smart slot, one of the following com-
munication cards can be inserted: AS-400 interface, SNMP for
controlling the equipment via Web or card for Internet or Intranet
managing.
Models from 4 to 10 kVA, allow the parallel connection of a
second equipment of the same features for a redundant configu-
ration or to increase the available power. This connection can be
done at any time and it does not condition the acquisition of itself.
Likewise, this power range has manual bypass.
It is possible to increase the standard back up time of the equip-
ment by connecting additional battery modules. In order to opti-
mise the recharging time of the batteries, there are equipments that
incorporate battery chargers with higher quality performances (B1).
This option (B1) is not available for power rates higher than 3 kVA.
The flexibility of this series to manage a wide range of IT devices,
it makes the best option to protect your LAN, servers, worksta-
tions and other electrical devices, and to ensure that your busi-
ness is protected against fluctuations of voltage, frequency,
electrical noises, blackouts and mains faults, which are present
in the energy distribution lines.
This manual is applicable to the standardised models stated in
table 2.
4.3.1. Main features.
• True on-line with double conversion technology and output
frequency independent from mains.
• Output power factor 0,9 and pure sinewave, suitable for al-
most any kind of loads.
• Input power factor > 0,99 and high general efficiency (be-
tween 0,87 and 0,9 for models 0,7 to 3 kVA and > 0,93 for
higher power rates). It is obtained both a higher energy
saving and lower cost of installation to the end-user (wiring),
as well as low input current distortion, therefore the pollution
in the power supply is minimised.
• High adaptability to the worst conditions of the input mains.

4.4. Options.
Depending on the selected configuration, the equipment can in-
clude any of the following options:
4.4.1. Isolation transformer.
The isolation transformer, provides a galvanic isolation that al-
lows isolating the output from the input completely.
The installation of an electrostatic shield between the primary
and secondary windings of the transformer provides a high level
of attenuation of the electrical noises.
The isolation transformer can be installed at the input or output of
the UPS from SLC TWIN RT series and it will always be located
out from the equipment enclosure.
4.4.2. External maintenance manual
bypass.
The purpose of this option is to isolate electrically the equipment
from mains and critical loads, without breaking the power supply
to the loads. Therefore, in this way the maintenance or fixing
tasks can be done in the equipment with no interruption on the
power supply energy to the protected system, at the same time
that unnecessary risks are avoided to the technical staff.
The basic difference between this option and the manual bypass in-
tegrated in the own UPS enclosure in models of higher power rate
than 3 kVA, consists in a better manoeuvring, because it allows a
complete disconnection of the UPS from the installation
4.4.3. Integration in IT networks by
means of the SNMP adaptor.
The big IT systems based on LANs and WANs that integrate
servers with different platforms, they have to include an easy
way of controlling and management at the manager system dis-
posal. This facility is got through the SNMP adaptor, which is
well-known by the main software and hardware manufacturers
The available SNMP option for SLC TWIN RT series is a card to
be inserted into the slot that the UPS has in its rear side.
The connection of the UPS with the SNMP is internal meanwhile
the connection between the SNMP and the IT network is done
through a RJ45 connector 10 base.
4.4.4. Relays interface card.
See section 4.3.10.3.
4.4.5. Parallel cable kit.
The parallel cable kit is used to make the parallel communica-
tion control between two equipments of the same power rate that
makes a system.
4.4.6. MODBUS protocol.
The big IT systems based on LANs and WANs, many times
they require that the communication with any device to be inte-
grated in the IT network has to be done by means of an industrial
standard protocol.
One of the most used industrial standard protocols in the market
is the MODBUS protocol. SLC TWIN RT series is also ready to
be integrated in this type of environments through the external
“SNMP TH card” device with MODBUS protocol.
4.4.7. Telescopic guide kit for rack
cabinet assembling in.
There is available only one model of telescopic guide kit for all
models, suitable for any type of rack cabinet.
These guides allow installing any unit of the TWIN RT equipment
and their possible battery modules, in case of extended back up
times, as it was a rack with its respective cabinet.

5. Installation.
• Check the Safety instructions (see chapter 2).
• Check that the data in the nameplate are the required by the
installation.
• A wrong connection or manoeuvring, can make faults in the
UPS and/or loads connected to itself. Read carefully the in-
structions of this manual and follow the stated steps in the
established order.
• The equipments can be installed and used by per-
sonnel with no specific training just with the help of this
«Manual» only, less those ones that are hardwired, which
have to be installed by qualified personnel.
• All connections of the equipment including the control
(interface, remote panel, ...), will be done with the
switches at rest and no voltage present (UPS power supply
switch to «Off»).
• Never forget that the UPS is an electrical energy gen-
erator, so the user has to take the needed cautions
against direct and indirect contacts.
• When there is only one equipment, omit all the instructions
of this document and their implicit connections as regards to
parallel systems.
• Parallel system installation needs a switchgear panel with sep-
arate input, output and static bypass protections, and a manual
bypass too.
This switchgear panel allows isolating only one equipment
from the system, when facing any malfunctioning and sup-
plying the loads with the rest of equipments during the pre-
ventive maintenance or during the reparation of itself, in
redundant systems.
Under request a manual bypass panel can be supplied for a
single equipment or a particular system.
• In parallel systems, the length and cross section of the
cables that go from the switchgear panel till each UPS
and vice versa, will be the same for all of them without any
exception.
• Battery circuit is not isolated from input voltage. Haz-
ardous voltages can be found out between the battery
terminals and earth. Check that there is not input voltage be-
fore doing any intervention on them.
5.1. To be considered in the
installation.
• Depending on the power of the equipment, there is a power
cord with plug or it is hardwired for input and IEC outlets or
hardwired for output, as connection parts for power. The rest
of connections are done through the connectors, including
the connection of the equipment with the battery module.
• Terminals for separate bypass line are only available in TWIN RT
models higher than 3 kVA .
• Cross cable section of the bypass, input and output lines,
will be calculated from the currents stated in the nameplate
of each equipment, and respecting the Local and/or Na-
tional Low Voltage Electrotechnical Regulations.
• Protections of the switchgear panel, will have the following
features:
For input and bypass lines, type B for RCD devices and
C characteristic for circuit breakers.
For the output (load feeding), C characteristic for circuit
breaker.
Regarding the size, they will be as minimum to the currents
stated in the nameplate of each UPS.
• In the nameplate of the equipment there are only printed the
nominal currents as it is stated in the safety standard EN-IEC
62040-1. To calculate the input current, the power factor and
the efficiency of the equipment have been considered.
Overload conditions are considered as nonpermanent and
exceptional operating mode.
• If it is added peripherals to the input, output and/or bypass
like transformers or autotransformers to the UPS, the cur-
rents stated in the own nameplates of those elements has to
be considered in order to use the suitable cross sections, by
respecting the Local and/or National Low Voltage Regulation.
• When an equipment incorporates a galvanic isola-
tion transformer, as standard, as an option or either
installed by yourself, either at the UPS input, bypass line,
output or at all of them, protections against indirect contact
has to be fitted in (residual current device) at the output of
each transformer, because due to its specification of isola-
tion it will prevent the triggering of the protections fitted in
the primary of the transformer in case of electrical shock in
the secondary (output of the isolation transformer).
• Remind you that all external isolation transformers al-
ready installed or supplied from factory, has the neutral
of the secondary connected to earth by means of a cable
bridge between both terminals. If it were required an iso-
lated output neutral, remove this cable bridge, keeping
the precautions stated in the respective local and/or na-
tional low voltage regulations.
• According to the most current trends, all the UPSs have
batteries inside the same rack enclosure of the equipment,
but in counterpart the resultant weight in the models from
4 to 10 kVA is notoriously high (see the stated weights in
the table 13 and/or in the own packaging of the equip-
ment).
Attend the recommendations stated in document
EK266*08 regarding to weight handling. Makes easy the
installation of this power range in a rack cabinet when the
handling labours are done manually, the battery block has
to be removed from the equipment according to the pro-
cedure described in section 5.2.4..
• Battery protection is by means of fuse and internal, so it is
no accessible by the end-user.
Battery modules have internal protections by fuse, and
they are not accessible by the end-user too.
5.2. Reception of the equipment.
5.2.1. Unpacking, content checking and
inspection.
• To unpacking, see section 5.2.3.
• On receiving the device, make sure that it has not suffered
any damage in transport (impact, drop, ...) and its features
correspond with the ones in the order, so it is recommended
to unpack the UPS and make a first visual inspection.
• In case of observing damages, make all pertinent claims to
the transport agency or in their lack to our company.
Never start up an equipment when external damages
can be observed.
14
• Also check that the data in the nameplate sticked in the pack-
aging and in the equipment, correspond to the ones stated
in the order, so it is required to unpack it (see section 5.2.3).
Otherwise, make a nonconformity as soon as possible, by
quoting the serial number of the equipment and references
in the delivery note.

to protect it against mechanical shocks, dust, dirt, etc...
5.2.2. Storage.
• Storage of the equipment will be done in a dry place, safe-
guard from rain, protected from dust, water jets or chemical
agents. It is advisable to keep the equipment and the battery
pack/s, into their original packages, which have been de-
signed to assure the maximum protection during the trans-
port and storage.
• In equipments that include Pb-Ca batteries, the figures,
stated in table 2 of the EK266*08 document, of charge
period time depending on the temperature that they are ex-
posed, must be respected, otherwise the warranty will be in-
validated.
• After this period of time, connect the equipment to mains and
together with battery module/s, if any, start it up according to
the instructions described in this manual and charge them
for 12 hours.
In equipments higher than 3 KVA ready for its parallel
connection, it is not needed to make the connection between
the equipments to charge the batteries. It can be treated as
separate units to charge them.
• Finally, shutdown the equipment, disconnect it and fit the UPS
and batteries in their original packaging, noting the new bat-
tery charge date on each respective label.
• Do not store the devices where the ambient temperature
exceeds above 50ºC or below –15ºC, otherwise it may de-
grade the electrical characteristics of the batteries.
5.2.3. Unpacking.
• The packaging of the equipment consists of a cardboard
enclosure, expanded polystyrene corner pieces (EPS),
polyethylene foam (EPE), polyethylene sleeve and band,
all of them are recyclable materials; therefore they should
be disposed according to current regulations. We recom-
mend to keep the packaging in case its use is necessary
in the future.
• Proceed as follows:
Cut the strips of cardboard enclosure.
Remove the accessories (cables, supports, ... )
Remove the equipment or battery module from the pack-
aging, keeping in mind that the it is needed the help of a
second person depending on the weight of the model or
use the suitable mechanical mediums.
Remove the protection corners from the packaging and
the plastic bag.
Do not leave the plastic bag at the children hand,
due to the risk that it means.
Check the equipment before proceeding and in case
damages where confirmed, contact with the supplier or
in lack of it with our firm.
5.2.4. Procedure to take out and install
the batteries in equipments of 4 to
10 kVA.
• According to the current trends, all the UPSs have batteries
inside the same rack enclosure of the equipment, but on the
contrary the resultant weight from 4 to 10kVA models is very
high (see weights stated in the table 13 and/or in the own
packaging of the own equipment).
Attending the recommendations stated in the document

When finalising the corresponding tasks, the cover will be
installed and its fixing screws again.
• It is recommended to use terminals in all the cable ends,
which are connected to the power blocks, specially in the
power ones (input, output and bypass).
• Check the correct torque in the screws of the power blocks.
5.3.1. Connection of input.
• As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth( )). Connect the conductor to
the terminal, before connecting the power supply to the input
power block.
• Equipments with IEC outlets (models from 0,7 to 2 kVA):
Take the power cord with schuko plug and IEC connector.
Connect the IEC connector to the UPS inlet.
Insert the schuko plug to the AC mains outlet.
• In equipments with power blocks (3 kVA B1 models).
Connect the power supply cables to input power blocks R (L),
and N, by respecting the phase and neutral rotation stated in
the labelling of the equipment and in this manual. If this
rotation is not respected, serious faults could happen.
The main earth input protection is located between
the phase and neutral terminal. Pay special attention
to the correct connection.
When discrepancies exist between the labelling and the in-
structions of this manual, the labelling will always prevail.
• For hardwired equipments (models from 4 to 10 kVA).
These equipments have separate power blocks for
the static bypass line. For installations with only
one power supply, place a cable as a bridge mode
"Jumper" between the terminals JP and L (bypass
phase line).
Do not fit this "Jumper" bridge, if the equipment is a
frequency converter (see figure 13).
In accordance with safety standard EN-IEC 62040-1,
the installation has to be provided with an automatic
«Backfeed protection» system, as for example a con-
tactor, which will prevent the appearance of voltage or
dangerous energy at the input line during a mains fault
(see figure 12 and respect the circuit diagram of the par-
ticular «Backfeed protection» for the equipment without
bypass line).
There can be no derivation in the line that goes
from the «Backfeed protection» to the UPS, as
the safety standard would be infringed.
It is not needed to install the «Backfeed protection»,
in case the equipment is a frequency converter, because
the own operating principle of the equipment disables the
possibility of having bypass line.
Warning labels should be placed on all primary power
switches installed in places away from the device to alert
the electrical maintenance personnel of the presence of
a UPS in the circuit be infringed.

• These equipments have separate power blocks for the
static bypass line. For installations with two power sup-
plies, the cable as a bridge mode "Jumper" between the ter-
minals JP and L (bypass phase line) are not to place,
otherwise a short-circuit can be made when turning on the
protection of both lines.
• As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth( )). Connect the conductor to
the terminal, before connecting the power supply to the input
power block.

5.3.3. Connection of the IEC outlets and
output power blocks.
• As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth( )). Connect the conductor to the
terminal, before connecting the power supply to the input
power block.
• All the equipments have female IEC outlets, in greater or lesser
numbers depending on the power rate of the equipment:
Models up to 2 kVA: 2 groups of 4 IEC outlets of 10A la-
belled as LS1 and LS2, which can be set through the con-
trol panel and/or Win Power.
Models of 3 kVA: 2 groups of 4 IEC outlets of 10A labelled
as LS1 and LS2, which can be set through the control panel
and/or Win Power, plus a IEC connector of 16A.
Models from 4 to 6 kVA: 2 groups based on 2 IEC outlets of
10A and 1 of 16A each one.
Each group has an automatic protection switch. In case
of tripping, the load connected to the respective outlet
has to be checked, otherwise the protection will be acti-
vated and deactivated cyclically, and therefore the loads
will suffer the consequences.
Models of 8 and 10 kVA: 4 groups based on 2 IEC outlets of
16A each one.
Each group has an automatic protection switch. In case
of tripping, the load connected to the respective outlet
has to be checked, otherwise the protection will be acti-
vated and deactivated cyclically, and therefore the loads
will suffer the consequences.
• For hardwired equipments (models from 4 to 10 kVA).
Connect the loads to output power block U (L) and N, by
respecting the phase and neutral rotation stated in the la-
belling of the equipment and this manual (see figure 13).
When discrepancies exist between the labelling and the
instructions of this manual, the labelling will always prevail.
Loads can be connected to the IEC outlets, to the
output power blocks or to both at the same time,
meanwhile the features of the equipment and IEC outlets
limitations are not exceeded, otherwise there will be
sudden blackouts in the power supply of the connected
loads at the output.
• If besides of the critical loads, it is required to connect lag-
ging loads of high consumption, like laser printers or CRT
monitors, the inrush currents of these peripherals will be kept
in mind in order to avoid blocking the equipment under the
worst conditions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.
• In parallel systems, the length and cross section of
the cables that go from the switchgear panel till one of
the UPSs and vice versa, will be the same for all of them
without any exception.
• With respect to the protection that must be placed at the
output of the UPS, we recommend that the output power
should be distributed in at least four lines. Each one should
have a circuit breaker protection switch of a value of one
quarter of the nominal power. This type of power distribu-
tion will allow that in the event of a breakdown in any of the
machines connected to the device causing a short-circuit, it
will affect to no more than the line that is faulty.
The rest of the connected loads will have their continuity as-
sured due to the triggering of the protection, because the
line affected by the short-circuit will trip its protection.
5.3.4. Connection of the external
batteries (extended back up time).
• As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth( )). Connect the conductor to
the terminal, before connecting the power supply to the input
power block.
• To not respect the safety instructions (see docu-
ment EK266*08) means a high risk of electrical
discharge and even the death.
• To connect the batteries with the equipment, follow the de-
scribed steps in sections 5.2.5.4 and 5.2.5.6.

• All the standard UPSs have batteries in the same enclosure,
less the B0 and B1. Battery protection is done by internal fuses
and not accessible for the end-user.
Battery modules have internal protections for the batteries
too and they are not accessible for the end-user.
• IMPORTANT FOR SAFETY: In case of installing the
batteries by yourself, the accumulators has to be pro-
vided with a two pole circuit breaker protection sized to the

Tabla 3. Specifications of the protection between the equipment and
battery module.
• Before starting the connection between the bat-
tery module/s and the equipment, check that the
equipment switch/es and the one in the battery cabinet
are in "Off" position.
Likewise when batteries are installed by own self, the
fuse or switch has to be turned off.
• Connection terminals of external batteries with the equip-
ment are done with a polarised Anderson connector.
• For battery connection with the equipment, follow the stated
steps in sections 5.2.5.4 and 5.2.5.6, keeping in mind the
model.
• In parallel systems (4 to 10 kVA models only), the connection
of the external battery modules with each equipment has to
be treated as single and separate units.
• Each battery module is independent for each equip-
ment. It is completely forbidden to connect to equip-
ments to the same battery module.
5.3.5. Connection of main input earth
terminal ( ) and the earth bonding
terminal ( ).
• As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth( )). Connect the conductor to
the terminal, before connecting the power supply to the input
power block.
• Make sure that all the loads connected to the UPS are only
connected to the protective earth bonding terminal ( ). The
fact of not restricting the earthing of the load or loads and/or
the batteries case/s or cabinet/s to this single point will create
a return loops to earth which will affect the quality of the sup-
plied power.
• All terminals identified as earth bonding ( ), are joined
together, to the main protective earthing terminal ( ) and
to the frame of the device.
5.3.6. Terminals for EPO (Emergency
Power Off).
• All UPSs have two terminal to install an external button, for
Emergency Power Off (EPO). Nevertheless, depending on the
power rate of the equipment, it is supplied a four pins connector
with the remote shutdown ON-OFF (models from 0,7 to 3 kVA)
or a single connector and individual of two pins (models from
4 to 10 kVA).
As an illustration mode, figures A and B, it is shown a con-
nector of two pins.
• By default, the equipment is supplied from factory with the
EPO circuit as closed (NC). So, the UPS will break the output
power supply, emergency power off, when opening the circuit:
Either by removing the female connector inserted in the
plinth. This connector has a cable bridge to close the cir-
cuit (Fig. A).
Fig. A Fig. B
Or by turning on the external button installed and be-
longing to the end-user. The connection in the button has
to be in normally closed because it will open the circuit
when turning it on.
• Through the control panel, it can be selected the reverse
functionality (Password required), normally open (NO).
Less punctual cases, it is not recommended to use this type
of connection due to the function of the EPO button, because
it would not work in case of any of the two cables that goes
from the button to the UPS were cut (damaged).
On the other hand this failure would be immediately detected
in the normally closed EPO type, with the inconvenience of
the sudden break in the power supply to the loads, but with
a complete guarantee of the functioning of the emergency
power off.
• To restore the normal operating mode of the UPS, the connector
with the cable bridge has to be fitted back in the terminal strip
or to deactivate the EPO button and later on to cancel the EPO
status in the control panel . The equipment will be operative.
5.3.7. "Dry_in" terminals, remote
ON-OFF (0,7 to 3 kVA equipments
only).
• The equipments from 0,7 to 3 kVA have a 4 pins connector,
two for the EPO (see the description in the previous section)
and two for remote start up or shutdown "Dry_in".
• Through these terminals, an external button can be con-
nected, with the same function that the own in the UPS.
• When pressing, over it for 1 second, the circuit will activate
the opposite order of the current status of the inverter, so, if
it is shutdown then it will be started up and vice versa, if the
inverter is started up then it will be shutdown (see figure 14).

5.3.8. "Dry_out" terminals, dry contact
for alarm (0,7 to 3 kVA equipments
only).
• The equipments from 0,7 to 3 kVA are supplied with a nor-
mally open dry contact "Dry_out", which is closed when
activating of any on or more associated alarms "Summary
Alarm" from Table 4.
• Do not apply more than 30V AC 1A or 60V DC 2A.

5.3.9. Connection in parallel.
5.3.9.1. Introduction to the redundancy.
N+1 is usually the most reliable power structure. N means the min-
imum quantity of equipments that the total load needs, so 1, and
1 means the quantity of redundant equipments, so it means, the
quantity of faulty UPSs that the system can allow at the same time.
TWIN RT series allows two equipment connected in parallel
only, for those models with power rate between 4 and 10 kVA, in
order to set a shared output and redundant in power.
5.3.9.2. Installation and parallel operating (4 to 10
kVA equipments only).
• Communication line (COM) is a very low voltage circuit
of safety. To preserve the quality, it has to be installed
separate from other lines that have dangerous voltages (energy
distribution line).
• Parallel connection bus. Use the bundle with 15 signal
cables with mesh and DB15 connectors in the ends to joint
up to 2 equipments as maximum. Each bundle has a male
and female connector in the ends, which will have to be con-
nected to joint both equipments. It is essential to close the
loop of the parallel bus.
The length of the parallel cable has 3 metres and it can't be
extended under any other concept due to the risk of interfer-
ences and communication failures that it could cause.
• The installation of the parallel systems, has to be provided
by a switchgear panel with individual protections for input,
output and static bypass (this last one, in those installations
that uses the second line only), also a manual bypass with
mechanical lock, see figures 16 and 17.
This switchgear panel allows isolating only one equipment from
the system, against any failure and feed the loads with the rest
of equipments during the preventive maintenance or its fixing. In
the same way, it allows removing an equipment in parallel and
replace it or put it in parallel again once it is fixed, but without
breaking the power supply to the loads meanwhile the con-
nected power can be supported by the operative equipment.
Under request a manual bypass panel can be supplied for a
single equipment or a system of two equipments in parallel.
• Respect the connection procedure for input and bypass de-
scribed in the previous sections of this chapter.
• Respect the established procedure to make the connection of
the battery modules for those equipments with extended back
up time, which has been described in the previous sections of
this chapter.
• Respect the established procedure to make the connection of
the output (loads), which has been described in the previous
sections of this chapter.
• Respect the established procedure to make the connection
of the output and batteries of the equipment, which has been
described in the previous sections of this chapter.
• In parallel systems, the length and cross section of the
cables that go from the switchgear panel till one of the
UPSs and vice versa, will be the same for all of them without
any exception.
In the worst case, the following deviations have to be strictly
respected:
When the distance among the UPSs and protection
panel is lower than 20 metres, the difference in the length
between the input and output cables of the equipments
has to be lower than 20%.
When the distance among the UPSs and the protec-
tion panel is higher than 20 metres, the difference in the
length between the input and output cables of the equip-
ments has to be lower than 10% .

5.3.10.1. RS232 and USB interfaces.
• Communication line (COM) is a very low voltage circuit
of safety. To preserve the quality, it has to be installed
separate from other lines that have dangerous voltages (energy
distribution line).
• RS232 and USB interfaces are used by the monitoring soft-
ware and firmware updating.
• It is not possible to use both ports at the same time.
• Signal pin-out of the DB9 connector are shown in table 5.

• USB communication port is compatible with the USB 1.1 pro-
tocol for communication software.
5.3.10.2. Smart slot.
• UPSs have a unique slot, hidden rear the cover stated in the
views of the equipment as "Smart slot", and allows inserting
any of the following options cards:
SNMP for control via Web.
Remote UPS management through Internet or Intranet.
Relays interface (for more details see the next section).
• For more information, contact with our S.T.S or our nearest
distributor.
5.3.10.3. Relays interface (option).
• Communication line (COM) is a very low voltage circuit
of safety. To preserve the quality, it has to be installed
separate from other lines that have dangerous voltages (energy
distribution line).
• UPS has a dry contact card for the relays interface commu-
nication protocol, it provides digital signals in a free potential
way, with a maximum applicable voltage and current of 240
V ac or 30 V dc and 1A.
• This communication port makes possible the dialogue be-
tween the equipment and other machines or devices, through
the 5 dry contacts supplied in the terminal strip included in
the same card and to each one of them an alarm of the 8
available can be assigned (see table 6).
Also there are other three additional terminals with only one
common, for an installation of an external On/Off switch to
the UPS and a third one with free setting among EPO, Shut-
down or "On-Off" remote control.
From factory all contacts are normally opened, being able
to set them separately one by one, by means of the Hyper
Terminal software or equivalent.
26
• The most common use of this type of ports is to provide the
needed information for the closing file software.
• This card has a RS232 port through a RJ connector. So, in
case of requiring a DB9 connector, use the adaptor RJ / DB9
supplied with the relays interface card.

• WinPower is a UPS monitoring software, which makes a
user-friendly interface of monitoring and management. This
software supplies an auto Shutdown for a system based on
several PCs in case of an electrical blackout. With this soft-
ware, the end-users can monitor and manage any UPS in the
same IT network, through the RS232 or USB communication
port, never mind the distance between them.
• Installation procedure:

5.3.12. Considerations before starting up
the connected loads.
• It is recommended to charge the batteries for 12
hours as minimum before using the UPS for first time.
When supplying voltage to the equipment, the battery
charger will automatically work.
• (B1) equipments with extended back up time has a
battery charger with higher quality performances. It is
recommended to charge the batteries for 12 hours as min-
imum before using the UPS for first time.
• Nevertheless, those equipments with extended back
up time and with no additional battery charger, it s rec-
ommended to charge the batteries of each battery module
for 12 hours.
• Although the equipment can work without charging the bat-
teries during the stated time without any problem, the risk of
a long blackout has to be valued during the first operating
hours and the available autonomy time in the UPS.
• Do not start up the equipment and loads completely till
chapter 6 states it.
Nevertheless, when it is done, it will be done gradually to
avoid any problem, as minimum in the first commissioning.

• If inductive loads with big inrush current apart from sensi-
tive ones are required to be connected like laser printers or
CRT monitors, keep in mind the start inrush currents of these
peripherals in order to avoid that the equipment becomes
blocked under the worst conditions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.

6.4. How to replace a faulty UPS in a
parallel system.
Press over the key in any UPS for more than 3 sec-
onds to shutdown all the inverters. The acoustic alarm
will beep for 3 seconds. The equipments that belong to
the current parallel system will transfer to "Bypass mode".
Put all the equipments on manual bypass. To do it re-
move the cover from manual bypass switch, which is
located at the back of each equipment and turn all the
switches to position "BYPASS".
Keep in mind that on "Bypass mode" or with the
switch on position "BYPASS", the loads will be
exposed to fluctuations of voltage, frequency and mains
faults or blackouts, so in case it were possible choose
one day with the lowest probability of faults (days without
fluctuations, days without storms,... ) and do it as fast as
possible.
Turn "Off" the input, output and bypass circuit breaker
protections (this last one when it is available) from the
protection panel and corresponding to the equipment to
replace.
Disconnect the communication bus and all power con-
nections, and remove it. In equipments installed as rack,
remove the screws that fix it to the cabinet previously.
Put the manual bypass switch of the new UPS, to position
"BYPASS". To do it remove the protection cover of the
manual bypass located in the rear side and act over itself.
Put the new equipment that replaces the faulty one and
reconnect it. Follow the instructions stated in section
5.3.9.2, to connect them in parallel.
For equipments installed as rack, put the screws that fix it
to the cabinet previously.
• Turn "On" the input and bypass circuit breakers (this last one,
if it is available) from protection panel, and corresponding to
the new UPS.
UPSs supply output voltage from bypass. Check the LCD
screen from control panel in case there were any warning or
error information.
Measure the output voltage of the new UPS, check the
voltage difference is below 1 V. In case the difference were
higher than 1 V, double check the wiring and associated in-
structions.
• Put back the cover of the manual bypass of each UPS.
• Press over the start up key for more than 3 sec. in any of
the UPSs and all of them will start up. All UPSs will transfer
to "Normal mode”.
Measure the output voltage in the power blocks of the parallel
system and the output terminals of the new UPS, to check
the voltage difference is under 0,5 V. In case the difference
were higher than 1 V, the UPSs have to be set (contact with
the S.T.S.).
• Press over the shutdown key in any UPS for more than 3
seconds and each one will be shutdown, supplying output
voltage through the bypass.
Turn “On” the output circuit breaker switch of the distribution
panel, corresponding to the new integrated equipment. The
complete parallel system will supply output voltage, through
the bypass.
• Remove the cover of the manual bypass in each UPS.
• Transfer the equipments with the manual bypass ("BYPASS"
position) to position "UPS". Do it in the switches of all equip-
ments.
• Put back the protection cover of the manual bypass switch
of all equipments, also check the torque of the fixing screws,
otherwise any of the limit contacts of this cover could be acti-
vated and the manual bypass too.
• Press over the start up key for more than 3 sec. in any
of the UPSs and all of them will start up, finally the parallel
system will be working on "Normal mode”.
Load/s are running and protected by the parallel system
again.
6.5. Manual Bypass Switch
(maintenance).
6.5.1. Operating principle.
Integrated manual bypass in all UPS from SLC TWIN RT from
4 to 10kVA is very useful, but a wrong use can cause irrevers-
ible consequences for both the UPS and connected loads at its
output. Therefore, it is important to respect the manoeuvring over
the switch as it is stated in the following sections.
6.5.2. Transference to maintenance
bypass.
• The procedure to transfer from normal mode to maintenance
bypass is the same for a single equipment or a parallel
system, less the quantity of actions:
For a single equipment.
–Press over the key of the UPS for more than 3 sec-
onds to shutdown the inverter. The acoustic alarm will
beep for 3 seconds. The equipment will transfer to
"Bypass mode".
For a parallel system.
–Press over the key in any UPS for more than 3
seconds to shutdown all the inverters. The acoustic
alarm will beep for 3 seconds. The equipments that
belong to the current parallel system will transfer to
"Bypass mode".
Put all the equipment/s on manual bypass. To do it re-
move the cover from manual bypass switch, which is
located at the back of each equipment and turn all the
switch to position "BYPASS.
In parallel systems, proceed in the same way in each
equipment.
Keep in mind that on "Bypass mode" or with the
switch on "BYPASS" position, the loads will be ex-
posed to fluctuations of voltage, frequency and mains faults
or blackouts, so in case it were possible, choose one day
with the lowest probability of faults (days without fluctua-
tions, days without storms,... ) and do it as fast as possible.
The UPS still supplies output voltage, from mains directly
or through the static bypass line (in those installations
that it is available), through the manual bypass of the
equipment.
Also, if the protection panel has manual bypass switch,
remove the mechanical lock and turn the switch "On"
(BYPASS).
In this case and in this case only, turn the output
switch/es from distribution panel to "Off", depending
if there is only one UPS or a system of two equipments
in parallel.
30
The UPS is completely shutdown and inactive and loads
are supplied through the manual bypass of the distribu-
tion panel.
6.5.3. Transference to normal mode.
• The procedure to transfer from maintenance bypass to
normal mode, is the same for a single UPS or parallel system,
less the quantity of actions to make:
If the protection panel has manual bypass switch:
–Turn the output circuit breaker protection/s of the dis-
tribution panel to "On" previously, depending if there
is a single UPS or a system of two equipments in par-
allel.
If the manual bypass switch is manipulated be-
fore turning "On" the output switch/es of the
protection panel, the power supply to the loads will be
break.
–Turn the manual bypass switch of the panel to "Off"
(UPS) and put the mechanical lock.
To avoid wrong manoeuvring the mechanical
lock has to be fit, otherwise the equipment and
loads are exposed to serious damages, even the de-
struction of both or fire.
Move the manual bypass switch to position "UPS" and
put the protection cover the manual switch back.
Put back the protection cover of the manual by-
pass switch of all equipments, also check the
torque of the fixing screws, otherwise any of the limit con-
tacts of this cover could be activated and the manual by-
pass too.
In parallel systems proceed with the same operations in
each equipment.
For a single equipment.
–Press over the start up key for more than 3 sec-
onds, the acoustic alarm will beep for 1 sec. and the
UPS will start up.
Load/s are protected by the equipment again.
For a parallel system.
–Press over the start up key for more than 3 sec-
onds in any of the UPSs and all of them will start up,
finally the parallel system will be on "Normal mode”
Load/s are protected by the parallel system again.

through the screen of the front panel.
• Immediately after the start up, the LCD panel shows the
SALICRU logo for few seconds and next the main screen
by default is displayed, where the status of the equipment is
represented (figure 21).
• When the same menu is displayed for 15 minutes in the LCD,
and there has not been any manipulation over the buttons, it will
return back to main screen automatically.
• The main screen shows the following information by default
Summary of the status, including the operating mode and
load.
Status of the alarm, if there is any one active.
The alarm includes the fault and warning informa-
tions.
Battery and status of the charge, including the battery
voltage, charge level and charger status.

Bypass with output voltage:
The output voltage that feeds the load comes from the
commercial mains directly through the internal filters.
This way the loads are not protected against mains faults
or blackouts. The acoustic alarm beeps every 2 minutes.
Fig. 24. Bypass with output voltage screen.
Bypass without output voltage:
The UPS is running on bypass mode without output
voltage.
Fig. 25. Bypass without output voltage screen.
ECO mode:
Once the UPS is started up, the energy that feeds the
load/s comes from the commercial mains directly through
the internal filters, meanwhile the voltage is inside the
limits that are set as normals.
When input power supply fails, due to fault or wrong,
the equipment will transfer from "Line mode" to "Battery
mode" to supply the load/s properly.
–This function can be activated through the control
panel (by means of password) or through a suitable
software (WinPower, ...)
–The transfer time between "ECO mode" and
"Battery mode" is around 10 ms. Neverthe-
less, this time can be excessive for some type of
loads, so the ECO mode operating has to be consid-
ered according to this issue.
Fig. 26. ECO mode screen.
Frequency converter mode.
Fig. 27. Frequency converter mode screen.
In the frequency converter mode, the static bypass is dis-
abled and any of the operating modes of itself, because
the input and output frequencies of the UPS are different
(50 or 60 Hz). When the input power supply fails, due
to fault or wrong, the equipment will transfer to "Battery
mode" to feed the load/s properly.
–This function can be activated through the settings
of the control panel (by means of password) or by
means of a suitable software (WinPower, ...)
–The power of the UPS will be the 80% of the nominal,
when it is running on "Frequency converter mode".
Warning.
When there is a "Warning", it means that there is some-
thing wrong in the UPS operating. Usually, the problems
are not serious and the equipment can be kept running.
However, pay attention to it, because the UPS could fail.
Fig. 28. Warning screen.
Fault.
When a fault occurs, it reveals that some serious prob-
lems have happened, the UPS will break the output
voltage or will transfer to bypass and the alarm will be
saved. The screen will change its blue colour to orange
as an intuitive warning mode.
Fig. 29. Fault screen.

Overload.
Fig. 30. Overload screen.
When the UPS is overloaded, an alarm is triggered with
a beeping of twice per second. Decrease the load level
connected at the output of the equipment, till the power
doesn't exceed from the nominal power of itself.
Battery test.
The UPS is running a battery test.

SALICRU
7.4.1. Operating on ECO mode.
7.4.1.1. Short description of the ECO mode.
• "ECO mode" function allows supplying the load/s from mains
directly, through the internal filters only, meanwhile the en-
ergy is inside the limits, so the UPS allows an "Economy
mode" and with high efficiency > 0,97.
• When mains is out of tolerances (voltage and/or frequency),
or there are mains failures or blackouts in the power supply,
the UPS will transfer to "Normal mode" or "Battery mode"
depending on the case and the load/s will be supplied in a
safety way.
• Nevertheless, the disadvantages are:
Load can't be protected at 100 %, because on "Line
mode" the load/s are supplied from commercial mains
directly and through the internal filters of the bypass.
The transfer time of the "ECO mode" to "Battery mode" is
10ms approximately.
Therefore, this function is not suitable for some sensitive
loads or areas with unstable power supply.
7.4.1.2. To establish the ECO mode function.
• The function can be activated or deactivated through the
“Setting” submenu (see section 7.3.7).

7.5.1.1. Short description of the frequency
converter function.
• In the converter mode, the static bypass is disabled and any
of the operating modes of itself, because the input and output
frequencies are different (50 or 60 Hz). When input mains
fails, either due to a blackout or wrong, the equipment will
transfer to “Battery mode” to supply the load/s properly.
• The output frequency is set to the preset value and required
by the loads. Nevertheless, the contra is the capacity of the
UPS, which is derated up to the 70% of the nominal in the
"Converter mode”.
7.5.1.2. To establish the Converter mode
function.
• The function can be activated or deactivated through the
“Setting” submenu (see section 7.3.7).

familiarised with them. Nobody else can manipulate them.
8.2. UPS Trouble Shooting guide.
If the UPS doesn't work properly, check the information given
by the LCD of the control panel, according to the models and
power of the equipment. Try to solve the problem by means of
the established steps in the tables 9 and 10. In case the problem
persists, consult with our Service and Technical Support S.T.S..
When it is needed to contact with our Service and Technical
Support S.T.S. , provide the following information:
• UPS model and serial number.
• Date when the problem occurred.
• Complete description of the problem, including the infor-
mation given by the led or LCD panel and the status of the
alarms.
• Power supply condition, type of load and the level connected
to the UPS, ambient temperature, cooling conditions.
• Information of the batteries (capacity and battery quantity), if
the equipment is (B0) or (B1) -with external batteries-.
• Other informations that you may think that they are important.
8. Maintenance, warranty
and service.
8.1. Battery maintenance.
• Pay attention to the safety instructions regarding battery (see
document EK266*08).
• The UPSs from SLC TWIN RT series only requires a
minimum maintenance. The used battery in the standard
models is lead acid, sealed, VRLA and maintenance free.
These models require a minimum of reparations. The only
requirement is to charge the UPS regularly, in order to pro-
long the battery lifetime. Meanwhile, it is connected to the
power supply, never mind if the UPS is ON or OFF, it will
keep the batteries charged and will give protection against
overcharging and undercharging.
• In equipments that include Pb-Ca batteries, the figures,
stated in table 2 of the EK266*08 document, of charge
period time depending on the temperature that they are ex-
posed, must be respected, otherwise the warranty will be in-
validated.
• Under normal conditions, the battery lifetime is from 3 to 5
years 25º C. In case that the battery was not in good condi-
tions, it has to be replaced before. This replacement has to
be done by qualified staff.
• Always replace them with the same quantity and type.
• Do not replace one battery only. All batteries have to be re-
placed at the same time and following the instructions of the
manufacturer.
• Usually, the batteries should be charged and discharged
every 4 or 6 months. The charging would be started after a
UPS shutdown due to a low battery (discharging). Charging
time for standard UPS should be 12 hours as minimum.
8.1.1. Notes for installing and replacing
the batteries.
• If it is needed to replace the connection of any wire, purchase
original parts through authorised distributors or service cen-
tres in order to avoid overheating and sparks with fire risk
because the size is not enough.
• Do not short the + and - poles of the batteries, there is risk of
fire or electrocution.
• Be sure that there is no voltage before touching the batteries.
Battery circuit is not isolated from the input. Hazardous volt-
ages can be found between the battery and earth terminals.
• Although the input and bypass circuit breaker switches (the
last one in 4 to 10kVA models with the respective power
supply mains) are turned off, the internal parts of the UPS
are still connected to the batteries, so there are hazardous
voltages inside.
Therefore, before doing any reparation or maintenance task,
the internal battery fuses have to be removed and/or the in-
terlink connections between them and the UPS.
• Batteries have hazardous voltages. The battery maintenance
and replacement have to be done by qualified personnel and

9.2. Glossary.
• AC.- It is nominated as alternating current (abbrevia-
tion in Spanish CA and in English AC) to the electrical
current in which the magnitude and direction varies in a
cyclic way. The most common wave shape of the alter-
nating current is sinewave, because the energy trans-
mission is better. Nevertheless, some applications
could need other period wave shapes, like triangular or
square.
• Bypass.- Manual or automatic, it is the physical junction be-
tween the input and the output electric device.
• DC.- The direct current (CC in Spanish, DC in English) is the
continuous electron flow through a cable between two points
with different potential. Unlike the alternating current, in direct
current the electrical loads always flow in the same direction
from the highest potential point to the lowest one. Although,
usually the direct current is identified with the constant cur-
rent (for example the one supplied by the battery), it is con-
tinuous any current that always maintain the polarity.
• DSP.- It is the acronym of Digital Signal Processor. A DSP is
a system based on a processor or microprocessor that has
instructions in it, a hardware and an optimised software to
develop applications where numerical operations are needed
with very fast speed. Due to this, it is very useful to process
analogical signals in real time: in a system that runs in this
way (real time) samples are received, usually coming from an
analogical/digital converter(ADC).
• Power factor.- It is defined as power factor, p.f., of an alter-
nating current circuit, as the ratio between the active power,
P, and the apparent power, S, or as the cosines of the angle
that make the current and voltage vectors, designating as
cos f, being f the value of that angle.
• GND.- The term ground, as its name states, refers to the po-
tential of the earth surface.
• EMI filter.- Filter able to decrease the electromagnetic inter-
ferences, which is the perturbation that happens in a radio
receptor or in any other electrical circuit caused by the elec-
tromagnetic radiation coming from an external source. Also
it is known as EMI, ElectroMagnetic Interference, Radio Fre-
quency Interference or RFI. This perturbation can derate or
limit the efficiency of the circuit.
• IGBT.- The Insulated Gate Bipolar Transistor is a semicon-
ductor device that is used as a controlled switch in power
electronic circuits. This device has the feature of the gate
signal of the effect field transistors with the capacity of high
current and low voltage saturation of the bipolar transistor,
combining an isolated FET gate for the input and a bipolar
transistor as switch in a single device. The triggering circuit
of the IGBT is as the MOSFET one, while the driving features
are like the BJT.
• Interface.- In electronic, telecommunications and hardware,
an interface (electronic) is the port (physical circuit) through
which are sent or received signals from a system or subsys-
tems toward others.
• kVA.- The voltampere is the unit of the apparent power in
electrical current. In direct current is almost equal to the real
power but in alternating current can defer depending on the
power factor.
• LCD.- LCD acronym of Liquid Crystal Display, device in-
vented by Jack Janning, who was employee of NCR. It is an
electric system of data presentation based on 2 transparent
conductor layers and in the middle a special crystal liquid
that have the capacity to orientate the light when trespassing.
• LED.- LED acronym of Light Emitting Diode, is a semicon-
ductor device (diode) that emits light almost monochrome
with a very narrow spectrum, it means, when it is direct polar-
ized and it is crossed by an electric current. The colour, (wave
longitude), depends on the semiconductor material used in
its construction, being able to vary from the ultraviolet one,
going through the visible spectrum light, to the infrared, re-
ceiving these last ones the denomination of IRED (Infra Red
Emitting Diode).
• Circuit breaker.- A circuit breaker or switch, is a device
ready to break the electrical current of a circuit when it over-
comes the maximum set values.
• On-Line mode.- Regarding to an equipment, it is on line
when it is connected to the system, and it is in operation, and
usually has its power supply turned on.
• Inverter.- An inverter, is a circuit used to convert direct cur-
rent into alternating current. The function of an inverter is to
change an input voltage of direct current into a symmetrical
output voltage of alternating current, with the required magni-
tude and frequency by the user or the designer.
• Rectifier.- In electronic, a rectifier is the element or circuit
that allows to convert the alternating current into direct cur-
rent. This is done by rectifier diodes, which can be solid state
semiconductors, vacuum or gassy valves as the mercury
vapour. Depending on the features of the alternating current
power supply used, it is classified as single phase, when they
are fed by a single phase electrical mains, or three phase
when they are fed by the three phases. Depending on the
rectification type, they can be half wave, when only one of the
current semi-cycles is used, or full wave, where both semi-
cycles are used.
• Relay.- The relay(in French relais, relief) is an electrome-
chanical device that works as a switch controlled by an elec-
tric circuit where, through an electromagnet, a set of contacts
are moved and it allows to open or to close other independent
electric circuits.
• SCR.- Abbreviation of «Silicon Controlled Rectifier», called
commonly as Thyristor: semiconductor device of 4 layer that
works as almost an ideal switch.
• THD.- They are the acronyms of «Total Harmonic Distor-
tion». The total harmonic distortion is done when the output
signal of a system is not equivalent to the one that enter into
it. This lack of linearity affects to the wave shape, because
the equipment has introduced harmonics that they were not
in the input signal. As they are harmonics, it means multiple
of the input signal, this distortion is not so dissonant and it is
more difficult to detect.
