in order to replace it.
CAUTION
The plates must not be removed or covered. No other plates may be affixed to the equipment without the Manufacturer's
prior written authorisation.
WARNING
Potential risks can be drastically reduced by wearing the Personal Protective Equipment listed in this chapter. These
protections are indispensable. Always operate with due care around dangerous areas marked by the appropriate warning
signs on the equipment.
2.6 General warnings
DANGER
The UPS works with dangerous voltages. Only SKILLED TECHNICIANS must perform the installation and ordinary
maintenance operations. No part of the equipment can be repaired by the operator.
Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel.
DANGER
Before beginning any installation and/or maintenance operation, make sure that all the DC and AC power sources are
disconnected.
The UPS must be installed with an earth connection to avoid high leakage currents. First connect the earthing cable.
Check during each installation and/or maintenance operation the continuity of the earthing system.
DANGER
The UPS is powered by its own DC energy source (batteries). The output terminals may have a dangerous voltage even if
the UPS is not connected to the AC power network.
The DC power source could comprise multiple battery drawers in parallel and/or external battery cabinets. Disconnect all
battery drawers and external battery cabinets before performing any installation and/or maintenance operation.
WARNING
A battery can present a risk of electrical shock and high short circuit current. The following precautions should be
observed when working on batteries:
a) remove watches, rings or other metal objects;
b) use tools with insulated handles;
c) wear rubber gloves and boots;
d) do not lay tools or metal parts on top of batteries;
e) disconnect the charging source prior to connecting or disconnecting battery terminals;
f) determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with
any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not
having a grounded supply circuit);
g) never leave live cables without an insulated protection.
Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. The batteries
installed inside the cabinet must be disposed of correctly. For the disposal requirements refer to local laws and relevant
standards.
12
CAUTION
The UPS functions with TT and TN systems. It has a pass-through neutral architecture: the status of the output neutral is
the same as the input neutral.
When a load needs a different neutral status from the input status, it is necessary to place downstream of the equipment
a suitably scaled isolation transformer protected in compliance with the standards in force.
For electromedical applications which require the medical IT system, it is necessary to have an insulation board
downstream the UPS that ensures compliance with the regulations in force for this type of application.
Due to the high leakage current to ground, Trimod HE cannot be powered by an IT system. It can only be used in an IT
system if the IT transformer is connected downstream of the UPS.
CAUTION
Do not open the battery fuse holders while the UPS is powering the loads in battery mode.
WARNING
To reduce the risk of fire or electric shock, the UPS must work in clean and indoor environments with controlled temperature
and humidity. It must be kept away from inflammable liquids and corrosive substances. The room temperature must not
be above +40°C (+104°F) and the relative humidity must be a maximum of 95% not condensing.
CAUTION
Trimod HE 10 is a category C2 UPS product. In a residential environment, this product may cause radio interference, in
which case the user may be required to take additional measures.
All the other Trimod HE models are products for commercial and industrial application in the second environment -
installation restrictions or additional measures may be needed to prevent disturbances.
The skilled technician must also:
- pass with a double turn, the cables connected to the backfeed terminals to a Fair-Rite toroid code 0431176451 made

4.2.2 Preliminary operations
Before connecting the UPS, check that:
• the mains input voltage and frequency correspond with the values indicated in the technical data on the rating plate;
• the earthing has been carried out in compliance with IEC standards or local regulations;
• the electrical system has been fitted with the necessary differential and thermal-magnetic protections upstream of the
UPS input.
4.2.3 Wiring
For all the models, it is possible to pass the cables from underneath, through the opening at the base. For the models
of Trimod HE from 10 kVA to 60 kVA, it is also possible to pass the cables from the metal plate fixed to the rear panel by
means of four screws. In this case it is necessary to lock the cables in place with appropriate cable glands, not supplied, to
be inserted in the holes of the plate. The plate has four holes 33 mm in diameter and one hole 16 mm in diameter.
In the case of the Trimod HE 80 kVA, the cables must be passed into the opening at the base. The fastening is done on the
appropriate bar by means of clamps and clips present in one of the accessory packs.
20
4.2.4 Earthing
Before carrying out any other installation operation, connect the earthing wiring coming from the low voltage switchgear
to the earthing terminal on the UPS terminal strip.
In the case of the Trimod HE 80, the earthing cables must be connected via cable lugs in the 8mm threaded holes on the
base, as shown in the following image:
4.2.5 Protective devices
To ensure proper protection from overloads or output short-circuits, it is necessary to use adequate protection at the
electrical system level.
Install automatic residual-current and thermal-magnetic breakers upstream of the UPS on the input line and on the
bypass line if separate), selected according to the indications in the tables shown in chapter 10.
4.2.6 Backfeed protection
The Trimod HE UPS is fitted with an auxiliary contact for the actuation of the external backfeed protection (protection
against power transfer towards the input). This auxiliary contact has been created with a C/NC/NO relay and is available
on the the relative tripolar “BACKFEED PROTECTION” terminal on the terminal strip.
If the UPS detects a voltage backfeed, the relay is energised and changes status, enabling the disconnection of the input
lines that must be done externally as indicated in the diagrams shown below.
The relay contacts characteristics are :
• Maximum applicable voltage: 250Vac.
• Maximum applicable current: 5A, cosφ = 1
INDICATION
If, during operation, the UPS signals that the backfeed protection has been actuated, contact the LEGRAND Technical

Trimod HE®
Installation and maintenance manual

DANGER
All the configurations and start-up operations must be done only by a SKILLED TECHNICIAN (paragraph 2.2.1)
5.1 Introduction
This chapter contains all the information necessary for a correct configuration of the UPS and for its subsequent startup.
The factory configuration provides for THREE PHASE INPUT and 120° THREE PHASE OUTPUT.
5.2 Input configuration
Trimod HE UPS automatically recognises the input voltage, frequency and number of phases if the electrical connection
on the terminal strip is modified.
CAUTION
Make sure the neutral wire is always connected.
5.3 Output configuration
Trimod HE UPS does not automatically recognise the electrical configuration on the output terminal strip. For this reason
it is always necessary to select the type of output voltage from the control panel according to the applied load.
The default configuration for the Trimod HE UPS is 120° three phase 400 Vac.
The UPS can also be configured to obtain a unique single output phase 230 Vac in the 10 kVA, 15 kVA, 20 kVA and
30-40 kVA TM models.
If the UPS is configured with three phase output, it is possible to select the management of the three phase as follows :
- THREE PHASES 120°: this is the default setup and is usually used if three phase loads are applied on the UPS output (e.g.
three phase electrical motors) or if there are both three phase and single phase loads powered by the UPS. In this case
the UPS manages the three output phases protecting the three phase load. For example, if an excessive load is applied
to one of the three output lines, the automatic bypass switches all three output lines.
- THREE SINGLE PHASE OUTPUTS: this setup is necessary if three single phase lines have been created with the common
neutral on the UPS output. In this case, the UPS manages the three outputs completely independently of each other. For
example, if an excessive load is applied to one of the three output lines, the bypass intervenes only on the overloaded
line while the power supply continues to be guaranteed on the other two by the UPS. If the input is single phase, the
three lines are not in phase but rather with a phase shift of 120° and therefore cannot be connected in parallel. If the
input is three phase, the outputs are in phase and the possibility of using the bypass is guaranteed.
For the correct selection of the output configuration, follow the instructions given in paragraph 5.5.
5.4 Pre-start-up checks
Before powering the equipment, carry out the following checks:
1. Check that the mains input switch S3 of the UPS is open (OFF position).
2. Check that the bypass input switch S5 of the UPS is open (OFF position).
3. Check that the battery fuse breakers of the UPS FB+ and FB- (if the model includes them) and those inside the external
battery cabinet (if present) are open (OFF position).
For the Trimod HE 30TT in which the fuse breakers are installed in the terminal strip, check that all the battery drawers
are not installed abutting and thus the string of batteries is interrupted.
4. Check that the maintenance bypass switch S1 and the output switch S2 of the UPS are open (OFF position)
5. Check that the wiring on input and output has been done and that all the connections have been tightened up properly.
6. Check the correct phase sequence of the mains input and bypass line (if separate).
7. Check that the parameters (voltage and frequency) of the input line are compatible with those shown on the UPS
rating plate.
8. Check that all the power modules are inserted properly and that the fixing screws of the power modules are present
and screwed up to abut the relative slots (use SHC M4x20 screws with hex socket head )
9. Check that all the battery drawers, if present, are inserted properly and that the fixing screws of the power modules are
present and all the fixing screws are screwed up to abut (use SHC M4x20 screws with hex socket head )
In the case of the Trimod HE 30 TT, push the battery drawers one at a time to abut and screw them up with the fixing
screws.

2. Check that the UPS is not functioning in battery mode and that the battery charger is in the "maintenance" or "standby"
state.
To check the status of the battery charger, go into the menu UPS Status Measures Batteries and check the
fourth item shown on the screen.
3. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer.
4. Insert the four new battery drawers and fix them with the screws provided with them.
5. Repeat steps 2, 3 and 4 for every KB to install/replace.
INDICATION
If the UPS switches to battery mode during the operation, do not extract nor insert battery drawers. It is possible to
resume the operation when the UPS returns to normal mode.
If during the operation the input mains power fails, the autonomy is reduced: it is therefore necessary to carefully assess
this circumstance in relation to the application before starting the procedure.
6.5.2 Installation/replacement of battery drawers with UPS in maintenance manual bypass
This procedure is valid for both models with internal batteries and for modular Trimod HE BATTERY.
1. Check that the procedure for placing in maintenance bypass mode described in the paragraph 6.4.2 has been applied.
2. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer.
3. Insert the four new battery drawers and fix them with the screws provided.
4. Repeat steps 2 and 3 for every KB to install/replace.
5. To leave the manual maintenance status actuate the procedure described in paragraph 6.4.2.
CAUTION
During maintenance bypass operations, the load is not protected because it is supplied from the bypass input line.
6.6 Extraordinary maintenance
Contact the LEGRAND Technical Support Service if there are failures that require the access to internal parts of the UPS.

DANGER
All storage operations must be carried out only by a SKILLED TECHNICIAN (paragraph 2.2.1)
DANGER
A SKILLED TECHNICIAN must check that there is no voltage present before disconnecting the cables. All the battery
breakers on the UPS and on the external battery cabinets must be open. The battery drawers of the Trimod HE
MODULAR BATTERY (if present) and of the UPS (according to the model) must be removed.
7.1 UPS
The UPS must be stored in an environment with a room temperature between -20°C (-4°F) and +50°C (+122°F) and humidity
less than 90% (not condensing).
7.2 Batteries
It is possible to store batteries without recharging them in the following conditions:
- up to 6 months if the temperature is between +20°C (+68°F) and +30°C (+86°F);
- up to 3 months if the temperature is between +30°C (+86°F) and +40°C (+104°F);
- up to 2 months if the temperature is over +40°C (+104°F).
CAUTION
The battery drawers or the external battery cabinets must never be stored if the batteries are partially or totally discharged.
