3 Introduction to Eaton UPS
Figure 1. Eaton 93PS UPS 8-20 kW and 93PS UPS 30-40 kW
The Eaton® 93PS uninterruptible power supply (UPS) is a true online,
continuous-duty, transformerless, double-conversion, solid-state, three-
phase system that supplies conditioned and uninterruptible AC power to
critical load and protects it from power failures.
The UPS is used to prevent loss of valuable electronic information,
minimize equipment downtime, and minimize the adverse effect on
production equipment due to unexpected power problems.
The Eaton UPS continually monitors incoming electrical power and
removes the surges, spikes, sags, and other irregularities that are
inherent in commercial utility power. Working with a building’s electrical
system, the UPS system supplies clean, consistent power that sensitive
electronic equipment require for reliable operation. During brownouts,
blackouts, and other power interruptions, batteries provide emergency
power to safeguard operation.
The UPS system is housed in a single, free-standing cabinet with safety
shields behind the door for protection against hazardous voltage. Each
UPS cabinet has a centralized system static bypass. The available static
bypass ratings are 20 kW and 40 kW. The static bypass size is chosen
according to UPS system power. For example, if a future requirement is
to upgrade the UPS capacity, the UPS bypass rating has to be selected
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 15 (117)
accordingly. In addition, the bypass ratings of all the UPS cabinets in a
parallel system need to be matched.
Eaton 93PS output power ratings are based on 20 kW rated
uninterruptible power modules (UPMs). A single UPS cabinet can house
one or two UPM modules to get ratings of 8 kW, 10 kW, 15 kW, 20 kW,
30 kW or 40 kW.
A UPM includes a rectifier, inverter, battery converter, and independent
controls. Each UPM is able to operate independently from the other
power modules.
NOTE: Startup and operational checks must be performed by an
authorized Eaton Customer Service Engineer, or the warranty terms
specified in the Warranty (see Chapter 10) become void. This service is
offered as part of the sales contract for the UPS. Contact service in
advance (usually a two-week notice is required) to reserve a preferred
startup date.

The system level static bypass in the Eaton 93PS UPS cabinet
determines the attainable output power of the UPS. The static bypass

line consists of a static switch and a backfeed protection isolation device
connected in series. In addition, there is a system level control unit that
constantly monitors the power delivered through the bypass line or to
the input of the UPS. Transfers to static bypass are seamless and
performed automatically by the system as needed, for example, in case
of an extended system overload.
Each UPM includes a rectifier, battery converter, inverter and
independent controls. Each UPM is able to operate and share the load
independently, despite the status of the other UPMs.
In addition, the system can have a UPS-internal maintenance bypass
switch as a factory-installed option.
The 8-20 kW 93PS UPS includes one UPM and internal batteries. It can
include a 20 kW or 40 kW rated static bypass. The 30-40 kW 93PS UPS
includes one or two UPMs, internal batteries and a 40 kW rated static
bypass. In addition to the internal batteries, external batteries can also
be connected.
In the 30-40 kW units, the UPMs are paralleled internally.
The rectifier input switch and battery breaker are available as standard
for all the models. The internal MBS is available as option for all the
models.
If utility power is interrupted or falls outside the parameters specified in
Chapter 9, the UPS uses a backup battery supply to maintain power to
the critical load for a specified period of time or until the utility power
returns. For extended power outages, the UPS allows you to either
transfer to an alternative power system (such as a generator) or shut
down your critical load in an orderly manner. The UPS bypass consists of
a continuous-duty static switch and a backfeed protection isolation
device. All the models also include an internal fuse in the bypass line.
The backfeed protection and bypass fuse are located in series with the
static switch.

3.2 UPS operating modes
The UPS operating modes are as follows:
• Normal operating modes:
• In the double conversion mode, the critical load is supplied by
the inverter, which derives its power from rectified utility AC
power. In this mode, the battery charger also provides charging
current for the battery, if needed.
• In the Energy Saver System (ESS) mode, the critical load is
supported securely by utility power through the static bypass
switch with double conversion available on-demand with
typically less than a 2 ms transition time, should any abnormal
condition be detected in the utility. When operating in the ESS
mode, the load is protected with inherent surge suppression.
Operating the UPS in the ESS mode increases system
efficiency up to 98.6%, allowing significant savings in energy
losses without compromising system reliability.
• In the stored energy mode, energy is drawn from a DC backup
power source and converted to AC power by the UPS inverter.
Most commonly VRLA batteries are introduced to the system
for this purpose, and the mode of operation is called the battery
mode.
• In the bypass mode, the critical load is supported directly by utility
power through the UPS static switch.
3.2.1 Normal operating modes
During normal UPS operation, power for the system is derived from a
utility input source. Unit Online is displayed on the front panel,
indicating that the incoming power is within voltage and frequency
acceptance windows.

Three-phase AC input power is converted to DC using a multilevel
converter with IGBT devices to produce a regulated DC voltage to the
inverter. The UPS status indicated on the display is Unit Online and
the UPM status is Active.
The battery converter derives its input from the regulated DC output of
the rectifier and provides regulated charge current to the battery. The
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 20 (117)
battery is always connected to the UPS and ready to support the inverter
should the utility input become unavailable.
The inverter produces a three-phase AC output to the critical load. The
inverter derives regulated DC from the rectifier and uses multilevel
converter technology with IGBT devices and pulse-width modulation
(PWM) to produce a regulated and filtered AC output.
If the utility AC power is interrupted or is out of specification, the UPS
automatically switches to the battery mode to support the critical load
without interruption. When utility power returns, the UPS returns
automatically to the double conversion mode.
If the UPS becomes overloaded or unavailable, the UPS seamlessly
switches to the bypass mode and continues supplying the load through
the static bypass. The UPS automatically returns to the double
conversion mode when the abnormal condition, such as an extended
time overload, is cleared and the system operation is restored within the
specified limits.
If a UPM within the UPS suffers an internal failure, the remaining UPMs
continue to support the load in the double conversion mode. The UPS is
automatically internally redundant when the UPS is not operating at full
load. However, if internal redundancy between the UPMs is not possible
due to high load, the UPS switches automatically to the bypass mode
and remains in that mode until the failure is corrected and the UPS is
back in operation.
In an external parallel redundant system, each UPS can be isolated from
the system for service while the remaining UPSs support the load in the
double conversion mode.

In the ESS mode, the UPS safely provides mains current directly to the
load when the input is within the acceptable limits by its voltage and
frequency. The UPS status indicated on the display is Unit Online
ESS, and the UPM status is Active. Surge protection and some filtering
is also provided, making sure that clean power is delivered to the load
equipment. In case any disturbances are detected in the incoming
power, the UPS switches to the double conversion mode and continues

to supply the critical load through its inverter. In case of a complete
utility outage or if the input power is outside the tolerances of the
system, the UPS transfers to the battery mode and continues to supply
conditioned, clean power to the critical load.
When operating in the ESS mode, the UPS's superior detection and
control algorithms continuously monitor the incoming power quality and
allow fast engagement of the power converters. Typical transition time
to the double conversion mode is less than 2 milliseconds, which is
practically seamless.
When the power conditions are within acceptable limits, the UPS
operates as a high efficiency, energy-saving system, providing surge
protection for IT equipment and making sure that clean power is
delivered to the facility. The energy saver system increases system
efficiency up to 98.6% when supplying 20-100% of nominal load,
reducing energy losses by up to 80%.
3.2.2 Stored energy and battery mode
When running normally in the double conversion or ESS mode, the UPS
automatically transfers to supply the load from batteries or some other
stored energy source if a utility power outage occurs, or if the utility
power does not conform to the specified parameters. The UPS status
indicated on the display is On Battery, and the UPM status is Active.
In the battery mode, the battery provides emergency DC power, which
is converted to regulated output power by the inverter.
Figure 6 shows the path of electrical power through the UPS system
when operating in the battery mode.

During a utility power failure, the rectifier no longer has an AC utility
source from which to supply the DC output current required to support
the inverter. The input relay K1 opens and the UPS output is powered
from the batteries through the inverter. As the inverter operates
uninterrupted through the transition, the load remains supported
continuously without disturbance. If the UPS static bypass is supplied
from the same source as the UPS rectifier, the backfeed protection
contactor K5 also opens. The opening of K1 and K5 prevent system
voltages from bleeding backwards and re-entering the input source
through the static switch or rectifier.
If the input power fails to return or is not within the acceptance windows
required for normal operation, the battery continues discharging until a
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 24 (117)
DC voltage level is reached where the inverter output can no longer
support the connected loads. When this event occurs, the UPS issues a
set of audible and visual alarms indicating that the batteries have a
minimal capacity left and a system shutdown is imminent. Unless utility
power is restored, the output can be supported for a maximum of 2
minutes before the output of the system shuts down. If the bypass
source is available, the UPS transfers to the bypass mode instead of
shutting down.
If the input power becomes available again at any time during the battery
discharge, K1 and K5 close and the UPS returns to normal operation. The
UPS also starts to recharge the batteries to restore the capacity.
3.2.3 Bypass mode
The UPS automatically switches to the bypass mode if it detects an
overload, load fault, or internal failure. The bypass source supplies the
commercial AC power to the load directly. The UPS can also be
commanded to transfer to the bypass mode manually through the
display. The UPS status indicated on the display is On Bypass.
Figure 7 shows the path of electrical power through the UPS system
when operating in the bypass mode.

In the bypass mode, the output of the system is provided with three-
phase AC power directly from the system input. While in this mode, the
output of the system is not protected from voltage or frequency
fluctuations or power outages from the source. Some power line filtering
and transient protection is provided to the load, but no active power
conditioning or battery support is available to the output of the system in
the bypass mode.
The static bypass consists of a solid-state, silicon-controlled rectifier
(SCR) static switch (STSW) and a backfeed protection isolation device
K5. The static switch is rated as a continuous-duty device that is used
anytime the inverter is unable to support the applied load. The static
switch is wired in series with the backfeed protection. As the static
Eaton 93PS UPS 8-40 kW User’s and Installation Guide

switch is an electronically-controlled device, it can be turned on
immediately to pick up the load from the inverter without interruption.
The backfeed protection is normally always closed, ready to support the
static switch unless the bypass input source becomes unavailable.
3.3 UPS features
The Eaton UPS has many features that provide cost-effective and
consistently reliable power protection. The feature descriptions provide a
brief overview of the UPS standard features.
3.3.1 Advanced Battery Management
The Advanced Battery Management technology uses sophisticated
sensing circuitry and a three-stage charging technique that extends the
useful service life of UPS batteries while optimizing the battery recharge
time. ABM also protects batteries from damage caused by high current
charging and inverter ripple currents. Charging at high currents can
overheat and damage batteries.
In the charge mode, the batteries are recharged. Charging lasts only as
long as it takes to bring the battery system up to a predetermined float
level. Once this level is reached, the UPS battery charger enters the float
stage and the charger operates in the constant voltage mode.
The rest mode begins at the end of the charge mode; that is, after 48
hours of float charging (user-adjustable). In the rest mode, the battery
charger is completely turned off. The battery system receives no charge
current during this rest period of approximately 28 days (user-adjustable).
During the rest mode, the open circuit battery voltage is monitored
constantly, and battery charging is resumed when necessary.
3.3.2 Powerware Hot Sync
The Eaton Powerware Hot Sync technology is an algorithm that
eliminates the single point of failure in a parallel system and therefore
enhances system reliability. The Hot Sync technology is incorporated in
all Eaton 93PS UPSs, and it is utilized in both multi-module internal
parallel and external parallel systems.
The Hot Sync technology enables all UPMs to operate independently in a
parallel system, even without inter-module communications. The power
modules utilizing the Hot Sync technology are completely autonomous;
each module monitors its own output independently to remain in
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 27 (117)
complete synchronization with the other modules. The UPM power
modules share the load perfectly even in changing capacity or load
conditions.
The Powerware Hot Sync technology combines digital signal processing
and an advanced control algorithm to provide automatic load sharing and
selective tripping in a parallel UPS system. The load share control
algorithms maintain synchronization and load balance by constantly
making minute adjustments to variations in the output power
requirements. The modules conform to demand and are not in conflict
with each other for the load. The Powerware Hot Sync systems are
capable of paralleling for both redundancy and capacity.
3.3.3 Power Conditioner
The Power Conditioner mode is characterized by the UPS running in the
double conversion mode without batteries connected. In the Power
Conditioner mode, the UPS provides conditioned output voltage and
frequency. The UPS can also support high nonlinear loads without ITHD
on the input. The UPS meets the qualifications outlined in the 93PS
product specification, except when the conditions below apply.
When in the Power Conditioner mode, the UPS has the following
functionality and limitations:
1. Run in the double conversion mode.
2. Because there is no battery, loss of utility results in the UPS losing
power and shutting down.
3. The UPS sustains up to -50% input voltage tolerance, unless the
current limit is reached.
4. If the rectifier is turned off, the UPS attempts a transfer to the
bypass mode.
5. The ESS mode is not available.
6. The Power Conditioner mode is available in both 3 and 4 wire
configurations.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 28 (117)
3.3.4 Frequency Converter
The Frequency Converter mode is characterized by the UPS running
without the bypass mode available. The output frequency can be
configured to be different from the standard input frequency (e.g. 60 Hz
output, 50 Hz input). The UPS can also support high nonlinear loads
without iTHD on the input. The UPS meets the qualifications outlined in
the 93PS product specification, except when the conditions below apply.
When in the Frequency Converter mode, the UPS has the following
functionality and limitations:
1. Operation is the same as when in the double conversion mode with
no bypass available.
2. Bypass alarms are suppressed.
3.3.5 Sync Control
The Eaton® Sync Control maintains the critical load outputs of two
separate single UPS systems in synchronization. Use of the Eaton Fixed
Master Sync Control provides uninterrupted transfer of the load from
one load bus to another by means of downstream, dual-source, solid-
state transfer switches. Without the load sync option, the two system
output (critical load) buses can become out of phase with each other.
This condition occurs when suitable bypass sources are not available or
when the bypass sources feeding each system are not in sync with each
other. Examples of this condition are two systems supplied by separate
generator sets, or situation where the bypass sources for the two
systems are lost.
3.4 Software and connectivity features
3.4.1 User interface
MiniSlot Communication Bays — there are 2 communication bays for
MiniSlot connectivity cards. MiniSlot cards are quickly installed and are
hot-pluggable. See Chapter 6 for additional information.
3.4.2 Power Management Software
Intelligent Power software products offer tools for monitoring and
managing power devices across the network. See Chapter 6 for more
information.

3.5 Options and accessories
Contact your Eaton sales representative for more information about the
available options and accessories.
3.5.1 Maintenance Bypass Switch (optional)
The Maintenance Bypass Switch (MBS) enables power to completely
bypass and isolate the UPS so that the UPS can be safely serviced or
replaced without interrupting power to critical systems.
An internal Maintenance Bypass Switch is provided as a factory-installed
option. Alternatively, MBS solutions are also available in an external
enclosure as accessory items.
External Maintenance Bypass Switch Panel (accessory)
The external MBS is enclosed in its own separate, wall-mounted cabinet.
The EMBS contains a rotary switch (MBP & MIS) to change the source
that supplies the load between the UPS output and the mechanical
bypass. It may additionally include two breakers: one for the rectifier
inputs (RIB) and another for bypass inputs (BIB). It may also include
auxiliary contacts to report the status of the switchgear to the UPS.
For external MBS installation instructions, see a separate manual.
3.5.2 Field installed UPM (accessory)
With a 30-40 kW 93PS UPS that has only one UPM installed, a Field
Installed UPM (FI-UPM) can be installed in the cabinet any time in the
future when power needs change. This enables the UPS system to grow
with the business, thus lowering the initial investment required for the
system on Day 1.
In order to install an FI-UPM, the UPS cabinet needs to have
upgradeability, which is determined by the power rating of the static
bypass. For example, if the static switch is rated for 40 kW and the UPS
includes one 20 kW UPM, it is possible to add another 20 kW UPM to it.
For a listing of the upgradeable configurations, see Table 1.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 30 (117)
CAUTION
Only qualified service personnel are allowed to install FI-UPM.
NOTE: Check the cable and fuse rating before power upgrades!
3.6 Battery system
The battery system provides short-term emergency backup power to
safeguard operation during brownouts, blackouts, and other power
interruptions. By default, UPS is configured to use VRLA batteries. If
other type of batteries or other energy storage means need to be
connected, consult a certified service technician prior to proceeding with
the installation.
The Eaton 93PS 8-40 kW UPS are equipped with internal batteries to
provide full load runtime of 5-60 minutes depending on the UPS rating.
In addition, external battery cabinets can be introduced to the system to
allow extended autonomy. Internal and external batteries can be used in
parallel.
For detailed battery specifications, see Chapter 9.
3.7 Basic system configurations
UPS power rating
The maximum attainable UPS system power rating is determined by the
size of the UPS cabinet frame. The number of UPM power modules
determines the nominal power rating of the UPS. If upgradeability is
required, the system static bypass should be chosen according to the
future maximum load rating, and the number of UPMs is chosen
according to the Day 1 capacity requirements.
The following UPS configurations with different static bypass sizes and
number of UPMs are possible:

The basic environmental requirements for the operation of the UPS
system are as follows:
• Ambient temperature range: from +0 to +40 °C
• Recommended operating range: from +20 to +25 °C
• Maximum relative humidity: 95%, non-condensing
It is required that ventilation of the UPS room is arranged. Sufficient
amount of air cooling is needed to keep the maximum room temperature
rise at the desired level:
• Temperature rise of +5 °C maximum requires the airflow of 600 m³
per 1 kW of losses.
• Temperature rise of +10 °C maximum requires the airflow of
300 m³ per 1 kW of losses.
An ambient temperature from +20 °C to +25 °C is recommended to
achieve a long life of the UPS and batteries. The cooling air that enters
the UPS must not exceed +40 °C. Avoid high ambient temperature,
moisture, and humidity.
For ventilation requirements, see 93PS heat rejection in Table 6.

UPS 40 kW, the minimum air flow is 6 m3/hour and the minimum free
area of opening for inlet and outlet is 168 cm2 when natural ventilation is
used. For larger batteries, the ventilation air flow must be recalculated.
Figure 9. 93PS 8-40 kW UPS dimensions
4.3.2 UPS system power wiring preparations
NOTE: If you are installing a maintenance bypass, provide one of the
following:
•
a minimum of 2 separate feeds with upstream feeder breakers
•
a single feed with 2 upstream feeder breakers: one for the UPS or
rectifier input breaker and one for the maintenance bypass input.
Do not use a single feed or a single feeder breaker to supply
•
the maintenance bypass and the UPS, or
•
the maintenance bypass and the rectifier input breaker.
If a bypass input breaker is installed in the maintenance bypass and a
single-feed UPS is being installed, a single feed to the maintenance
bypass is acceptable for supplying both the UPS and the bypass.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 39 (117)
When you plan and perform the installation, read and understand the
following notes:
• Refer to the national and local electrical codes for acceptable
external wiring practices.
• To allow for future kVA upgrades (software and/or hardware),
consider using conductors that are sized for the full bypass rating of
the UPS.
• Material and labor for external wiring requirements must be
provided by designated personnel.
• For external wiring, use copper cable rated for 70 °C at minimum.
See the appropriate information in Table 7. Cable sizes are based on
using the specified breakers.
• If cables are run in an ambient temperature greater than 30 °C,
higher temperature cable and/or larger size cable may be necessary.
• The bypass feed into this equipment uses four cables. The rectifier
feed into this equipment uses three or four cables. The phases
must be symmetrical about ground (from a Wye source) for proper
equipment operation.
• If the load requires a neutral, a bypass source neutral must be
provided. If the load does not require a neutral and there is no
neutral conductor connected at the bypass input, a neutral must be
installed to source star point.
• A readily accessible disconnect device must be incorporated in all
fixed input wiring.
WARNING
Do not disconnect the bypass neutral without disconnecting the
bypass phases at the same time.

5.2 Battery system installation
.
DANGER
This UPS may have internal batteries. The batteries are designed to
deliver a large amount of energy and an incorrect connection may lead
to a short circuit and cause serious injuries to the personnel or
damages to the equipment. In order to avoid damages to the
equipment or injuries to personnel, only commissioning personnel are
allowed to perform the connection of these batteries.
If installing a customer-supplied battery system, install the battery
system according to the battery and battery system manufacturer’s
instructions and all the applicable national codes and regulations. Only
qualified personnel may install the battery system. Battery cables must
be protected against current and thermal overload, that is, the battery
system must include proper fuses or breaker with protection function.
Ground the external battery cabinet to the UPS.
The default battery settings of the UPS are for 12 V VRLA batteries. If
other battery types are to be used, contact your Eaton representative.
For the battery specification, see Section 9.5.
5.2.1 Battery trip wiring
The 93PS 8-40 kW UPS units are always equipped with an internal
battery breaker, which affects only the UPS internal batteries. The
external battery breaker is a crucial part of the external battery cabinet or
rack and must be placed in it. With the external battery breaker, signal
cabling is important.
Both internal and external battery breakers can be tripped (switched off)
by energizing its shunt trip coil. The shunt trip coils of external battery
breakers are energized (controlled) through connectors TB20 and TB21
(TB21 available only in the 30-40 kW UPS). The default voltage of the
shunt trip coil is 24 Vdc.

5.3 Installing UPS external battery cabinet and battery
power cabling
For the 93PS product line, there are two different battery cabinets: EBC-
S and EBC-L. The 93PS 8-40 kW UPSs use 32 battery blocks per string.
NOTE: Do not connect battery strings with different battery quantity and
voltage in parallel.
Power and control wiring for the EBC-S and EBC-L cabinets are supplied
with the cabinets. The battery cabinet can be located freely of the 93PS
UPS cabinet. All the wiring goes through the back wall of the UPS
cabinet.
For instructions on how to install the external battery cabinet and battery
power cabling, see the instruction manual provided with the external
battery cabinet. Earth the external battery cabinet / customer-supplied
battery system to the PE terminal 16 shown in Figure 10 and Figure 11.
NOTE: If batteries are wired outside the cabinets, follow the installation
instructions given in Section 4.3.2. See Table 7 for the recommended
cable and fuse sizes.
5.4 Installing a remote EPO switch
A remote EPO switch can be used in case of an emergency to shut
down the UPS and remove power to the critical load from a location
away from where the UPS is installed.
EPO is connected to the UPS's top front panel, on connector EPO.
Figure 16 shows the NO and NC connections of the EPO switch.

5.5 Installing interface connections
93PS UPS contains a total of 5 signal input connectors for operators
which can be used for giving remote control commands to the UPS.
User interface connector TB1 can be used for these purposes. Each
input is a dry relay contact input and requires two-wire signaling. None of
the inputs are pre-programmed but need to be separately programmed
by qualified service personnel.
When using an external battery system (either the original 93PS battery
cabinet or a customer-sourced battery cabinet/rack), external signaling
wiring is recommended to be connected.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 58 (117)
One general alarm relay output is also on the front panel. This output is
either normally open (NO) or normally closed (NC). The polarity selection
is made with a wiring connection. By default, the general alarm relay
activates when a system alarm is active, that is, any ALARM condition is
active in the system. Alternatively, it can be activated with any particular
event, but this must be programmed separately by qualified service
personnel. The alarm relay is designed for signal level (ELV or SELV)
voltages only, not for utility use. For higher signaling circuit voltage
requirements, please use an industrial relay adapter in the MiniSlot.
5.5.1 Installing customer input signal interface
These inputs are located behind the UPS door, in the top section of the
UPS. See Figure 22 for the connector locations.
Tie points with strain relief for the communication cables are located on
the right and left side of the cable conduit.
Signal inputs can be configured to different functions. Normally these
functions are either informative (for example, “On Generator”) or
functional (for example, a remote “Go to bypass” command).
5.5.2 Battery breaker wiring interface
When using the original accessory battery cabinet from the
manufacturer, the battery breaker interface wiring is provided with the
cabinet. Connecting it requires only routing the wires from the cabinet to
terminal TB20 (and TB21). In 93PS 8-20 kW UPS, the connector for the
battery circuit breaker monitoring signal and battery circuit breaker trip
signal is on the left side of the power cabling.
When using a third-party battery system, the breaker must be equipped
with auxiliary signal and should have a 24 V shunt trip for remote
opening of the breaker, when needed.
Wire entry for the battery breaker signal wiring is located in the middle
of the UPS cabinet. Punch holes are located on the left or right side
panel, back wall or bottom plate.
See Section 5.2.1 for installation instructions.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 59 (117)
5.5.3 Relay output interface connections
The general alarm relay is a dry relay signal output. The relay can be
used for informing the operators about UPS alarm conditions, for
example through a building management system. By default, the relay is
configured to activate when the UPS general alarm is active, that is, any
event when the ALARM status is active. The relay can also be
configured to activate by some other event, but this needs to be done by
authorized service personnel.
Relay signal wiring can be installed only through the signal cabling canal,
from back to front, in the top section of the UPS.
Additional relay outputs are available with mini-slot cards. Relay outputs
can be configured by a service engineer to be activated by various
events.
5.5.4 Industrial Relay Card interface connections
Relays K1 through K5 are identical in function. Each output contact
function can be assigned by the user. The UPS information may also be
configurable.
To install the INDRELAY-MS:
1. Check that the ancillary equipment system is turned off and all the
power sources are removed. Refer to the appropriate operation
manual of any ancillary equipment for shutdown instructions.
2. Install wiring from the IRC to the monitoring equipment using
appropriate conduits through the cable exit opening in the IRC.
3. Connect wiring between the IRC terminal blocks and the monitoring
equipment using terminations. Connect one wire to COM
(Common) and another to either NC or NO to select the Normally
Open or Normally Closed option.
4. Install the INDRELAY-MS into an open MiniSlot communication bay
in the UPS cabinet.

1. If not already installed, install the LAN drops.
2. Open the front door of the UPS.
3. To remove the MiniSlot cover plate, remove the 2 screws securing
the plate.
4. To install the MiniSlot communication device, push it all the way in.
5. Secure the MiniSlot communication device with 2 screws.
6. Route and install the LAN and other cables to the appropriate
MiniSlot cards. The cable route is through the signal cable canal in
the top section of the UPS.
7. For operator instructions, refer to the manual supplied with the
MiniSlot card.

5.5.6 Installing signal interface connections in a parallel
system
The installation of the signal interface connections in a parallel system is
done by following the aforementioned instructions. Signal inputs can be
paralleled between the units, that is, the same contact can be used for
several units’ signal input signaling. This concerns also the EPO signal.
5.6 Wiring parallel 93PS UPS systems
The outputs of multiple 93PS UPS systems can be connected in parallel.
Up to 4 units can be paralleled. The UPS static bypass power rating
needs to be identical among all the paralleled units. However, paralleled
UPS cabinets can be housed with different number of UPM power
modules.
The outputs are paralleled to increase the load capacity of the power
system and for redundancy. The system is paralleled for (N+1)
redundancy as long as there is always one or more UPS online than
required to support the load. The system is paralleled for capacity if all
UPSs in a system are required to support the load.
Communication between the UPSs is required for system metering and
mode control. The system level communication and control are
accomplished using a Controller Area Network (CAN). A pull-chain signal
in each UPS, connected to the other UPSs in parallel and tied to the
bypass status relay in each UPS, is used for a secondary communication
path. This arrangement ensures bypass control even if the CAN bus is
lost.
WARNING
Do not connect in parallel units which are equipped with an internal
Maintenance Bypass Switch (MBS).

The input feed is defined as the power source connected to the UPS
rectifier. The feed to all UPS’s inputs must be derived from the same
source.
Bypass feed
The bypass feed is defined as the power source connected to the UPS
bypass. The feed to all UPS’s bypass must be derived from the same
source. The shortest length of power wire from the source to the UPS
must be a minimum of 95% of the length of the longest wire.
Output
The neutrals of all the UPSs must be connected. The shortest length of
wire from the source to the UPS must be a minimum of 95% of the
length of the longest wire. The measurement is with respect to where
the UPS’s outputs are tied.
Dual source
The input feed and bypass feed may be separate sources. The sources
must share a common neutral.
Battery connection
A separate battery shall be connected to each UPS, and the battery
capacity for each UPS must be identical. A common battery for all UPSs
is not supported.
MOBs
Module Output Breakers (MOBs) allow the output of an UPS to be
disconnected from other UPSs and the system load for maintenance and
service. Design considerations assume that each UPS has a Module
Output Breaker (MOB). The breaker should also disconnect the neutral
for improved safety during maintenance.
The MOB must have a Form “C” auxiliary contact. The N.C contact is
connected to the corresponding UPS’s input used for signal input. The
N.O. contact is used to disconnect the bypass pull-chain when the MOB
is open. Figure 18 shows the principles of paralleled UPS systems
including MOBs and outputs from UPSs.

MOB override
Users without MOBs installed can simply leave the MOB signal input
disabled. The user should be aware that systems without MOB have
limited maintenance capability.

The required parallel system wiring length must be equal to ensure
approximately equal current sharing when in the bypass mode.
For proper operation, the following must be true:
1A+1B=2A+2B=3A+3B=4A+4B.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 64 (117)
Any differences in wire length result in decreased capacity and improper
operation of the UPS system while in the bypass mode.
5.6.2 Control signals overview
2 controls signals (External CAN Network, Bypass Pull-Chain) are
required for external paralleling. Both of these control signals are fault-
tolerant and alarmed when disconnected.
External CAN (ECAN)
ECAN provides means for communication between the UPS’s in a
parallel system. When this network fails, the system continues to share
load and protect the load.
Bypass Pull-Chain
Bypass Pull-Chain is an open collector signal that goes low when the
bypass static switch of any UPS is online. When External CAN (ECAN) is
down, the pull-chain is low and the UPS is online, the UPS locks to and
transfers to the bypass mode. Service can manually short this signal in
some rare failure modes to force a system transfer to bypass.
Signal Inputs Actions
Each UPS has a maximum of 7 signal inputs, 5 native and one in each
MiniSlot when using a suitable connectivity device. These inputs can be
configured with action items. The following action items affect all the
UPSs in the system. When an action item is active on a UPS and the
MOB is closed, the action item is transmitted on the ECAN to all the
UPSs. All the UPSs react in the same manner as if the action item was
active on that UPS.
Wiring the EPO switch in parallel
It is recommended to use separate EPO circuits for each parallel unit.
5.6.3 Installing bypass control wiring
1. During the installation, follow all the safety instructions given in this
document.
2. Terminal blocks TB6, TB7 and TB8 are for external parallel control
signals (see Figure 20 and Figure 22).
3. The Phoenix Contact FRONT-MSTB 2,5/2-STF-5,08 and 2,6/4-SFT-
5,08 plug components are used for cable wiring termination.

leads, use the same wire gauge to connect to the UPS and use the
correct crimp connections for the wire gauge. External CAN connections
between the UPS cabinets require shielded twisted pair wire. Use
twisted pair wiring between the UPS and MOB AUX contacts. Always
confirm contact operation prior to wiring.

5.7 UPS system interface wiring preparations
Control wiring for features and options should be connected at the user
interface terminal blocks located on top front of the UPS, behind the
door.
NOTE: Do not connect relay contacts directly to the mains-related
circuits. Reinforced insulation to the mains is required.
When you are planning and performing the installation, make sure you
understand the following notes:
• All the interface wiring is provided by the operator.
• When installing internal interface wiring to MiniSlot terminals, route
the wiring through the internal opening in the MiniSlot
communication bay.
• All signal inputs or remote features require an isolated normally-
open contact or switch (rated at 24 VDC, 20 mA minimum)
connected between the alarm input and the common terminal. All
control wiring and relay and switch contacts are supplied by the
operator. Use twisted-pair wires for each alarm input and common.
• The signal inputs can be programmed to display the alarm's
functional name.
• LAN drops for use with MiniSlot cards are provided by facility
planners or the operator.
• The UPS Battery Aux and 24 VDC Shunt Trip signal wiring from the
UPS must be connected to the DC source disconnect device. See
Figure 14.
• Battery Aux and 24 VDC Shunt Trip wiring must be a minimum of
1.5 mm².
• The Remote EPO feature opens all switchgear in the UPS cabinet
and isolates power from your critical load. Local electrical codes
may also require tripping upstream protective devices to the UPS.
• The Remote EPO switch must be a dedicated switch that is not tied
to any other circuits.
• If the normally-closed (NC) Remote EPO contact is used, a jumper
wire must be connected between pins 1 and 2 on connector EPO.
• Remote EPO wiring should be a minimum of 0.75 mm² and a
maximum of 2.5 mm².

6.2 Intelligent Power Software
Intelligent Power Software are productivity tools for UPS power
management. These software solutions enhance the protection provided
by a UPS by shutting down applications and operating systems,
triggering disaster recovery procedures and migrating virtual machines in
case of an extended power outage. They also help in reducing downtime
and increasing the reliability of the UPS by alarming the operators of
issues and monitoring vital meters. The software can also be used to
view the usage characteristics of power equipment across the
enterprise and use the data to optimize the use of the facilities.
Intelligent Power Software is web-based, which means that the
information can be accessed through any device that has a web
browser.
On one hand, Intelligent Power Manager (IPM) is a monitoring system
that can concentrate the data and alarms of hundreds of UPS, ePDU and
other devices into a single view. On the other hand, it provides a link to
virtualization through management systems, such as VMware vCenter.
This way an administrator gets a single pane of glass to manage both IT
equipment and the supporting infrastructure. IPM provides the
shutdown, migration, disaster recovery and load shedding features in
virtualized environments.
Intelligent Power Protector (IPP) is a shutdown agent with basic
monitoring and alarming capability. It provides automatic, graceful
shutdown of computers and virtual machines or servers powered by an
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 74 (117)
Eaton UPS during a power outage that lasts longer than your available
battery runtime. Intelligent Power Protector can be remotely supervised
and managed by the Intelligent Power Manager (IPM) application.
Intelligent Power Software is delivered on a CD with the UPS.
Alternatively, you can download it from the Eaton web page. Some of
the advanced features of IPM require a license, contact your Eaton
representative for details.
6.3 Signal input monitoring
This standard feature lets you connect smoke detectors or over-
temperature alarms to your signal inputs. The user interface terminals
for external connections are located inside the UPS. Use twisted-pair
wires for each alarm input and common.
The signal inputs can be programmed to display the alarm functional
name.
6.4 General purpose relay contact
One general purpose relay contact is provided as a standard feature on
the UPS. An alarm contact is also provided.
You can use a normally-closed or normally-open contact. If the state of
the contact changes from the state you specify as normal, a signal is
issued. You can connect this contact to equipment at your facility (such
as a light or an alarm bell) to let you know when an alarm is active on the
UPS. This feature is useful if the UPS is located in a remote area where
the UPS horn may not be heard immediately.
NOTE: Do not operate the contacts in excess of 30 VAC (RMS) and
30 VDC at 5 A maximum.
6.5 Configuring relays
93PS offers one native relay output. Additionally, each of the 2 MiniSlots
can be equipped with a relay card, including 5 relays. The following
instructions guide you through the relay configuration.
Currently the relay configuration can be done only using the display. The

8 UPS maintenance
The components inside the UPS cabinet are secured to a sturdy metal
frame. All repairable parts and assemblies are located for easy removal
with very little disassembly. This design allows authorized service
personnel to perform routine maintenance and servicing quickly.
Schedule periodic performance checks of your UPS system to keep it
running properly. Regular routine checks of the operation and system
parameters enable your system to function efficiently for many trouble-
free years.
8.1 Important safety instructions
Remember that your UPS system is designed to supply power
EVEN
WHEN IT IS DISCONNECTED FROM THE UTILITY POWER
. The UPS
module interiors are unsafe until the DC power source is disconnected
and the electrolytic capacitors are discharged.
After disconnecting the utility power and the DC power, authorized
service personnel must wait at least 5 minutes for capacitor bleed-off
before attempting internal access to the UPS module.
.
DANGER
LETHAL VOLTAGE. Do not operate the UPS system without the
cabinet doors or protective panels secured. Do not make any
assumptions about the electrical state of any cabinet in the UPS
system.
WARNING
All service and maintenance work must be performed only by service
personnel qualified and authorized by Eaton.
Eaton 93PS UPS 8-40 kW User’s and Installation Guide
© Eaton Corporation plc 2015. All rights reserved. Revision: 002 Document ID: P-164000493 103 (117)
CAUTION
An additional warning label, shown in Figure 37, must be installed at
the UPS input terminals and all the primary power isolators used to
isolate the UPS unit if the UPS input is connected through external
isolators that, when opened, isolate the neutral. These warning labels
can be obtained from your local service representative.
Figure 37. Warning label
Since each battery string is an energy source in itself, opening the
battery circuit breaker does not de-energize the voltage within the
battery string.
. DANGER
Do not attempt to access any internal area of the battery string
yourself. Voltages are always present in the battery strings. If you
suspect that a battery string needs service, contact your service
representative.
Observe these precautions when working on or around batteries:
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries or battery
cabinets.
• Prior to connecting or disconnecting terminal, disconnect the
charging source.

• Determine if the battery is inadvertently grounded. If it is, remove
the source of the ground. Contact with any part of a grounded
battery can result in an electrical shock. The likelihood of such a
shock is reduced if such grounds are removed during installation
and maintenance.
• When replacing batteries, use the same number of sealed, lead-acid
batteries.
• Dispose of batteries according to your local codes for disposal
requirements.
8.2 Performing preventive maintenance
The UPS system requires very little preventive maintenance. However,
inspect the system periodically to verify that the units are operating
normally and that the batteries are in good condition.
The majority of the service and maintenance work must be performed
by service personnel qualified by Eaton. Only the actions described in
Section 0 and Section 8.2.3 are allowed to be performed by the user.
