2.1 Trimod® Technology
Congratulations on your purchase of a UPS Trimod® product from LEGRAND®.
Thanks to the UPS Trimod® your critical equipment will be protected by a constant and reliable supply of power for years
to come.
LEGRAND® has developed a project that is both innovative and unique, creating Trimod®, the UPS with a power range
of 10, 15, 20, 30, 40 and 60 kVA capable of adapting itself at any time to the changing requirements of protected loads:
greater power, longer autonomy, redundancy.
The basic concepts of the Trimod® project are, in fact, modularity, expandability and redundancy which, besides oering
maximum reliability, are also the guarantee of a considerable economic saving.
Trimod® is a modular uninterrupted power supply unit with individually programmable basic modules so you can have
the input/output conguration you want. In this way it is possible to control three- and single-phase voltage in input and
output to have, as preferred the classical three/three, three/single, single/three and single/single lines but it is not limited
to just this: you can also have single- and three-phase lines in output simultaneously or two or more single-phase lines
also of dierent powers (on request).
And then, for each conguration it is possible to obtain redundancy, both complete and partial by which we mean that,
for example, a normal (or redundant) threephase line plus a redundant (or normal) single-phase line can coexist in output.
A microcontroller mounted in each basic module is capable of monitoring the main functions of each single power unit,
monitoring its correct operation and signalling any malfunctions.
The modularity philosophy has also been used for the batteries which are supplied in single pull-out boxes. THDi = 3% Power Factor > 0.99 – High Yield – High Reliability – Easy to install and service.
2.2 Features
Redundant modular architecture
Redundant modular architecture is the best way to protect a company’s critical points.
Advantages:
- There is just one control of the devices powered
- Modular Expandability
- Module redundancy
- Easy to service
- Low running cost
- Compact size
Yield
The UPS units of the Trimod® line place particular attention on the energy taken from the mains and that supplied to the
user points. High Yield (>94%), PFC in Input >0.99, THDi 3%.
Advantages:
- Increasing the yield means reducing the part of power absorbed by the UPS but not supplied at the load and transmitted
to the environment in the form of heat.
- Les s heat dispersed in the environment means reducing the use of aeratin g or conditioning systems on the installation premises.
- PFC in input means no rephasing costs and consequently no increased rates.
- No need to oversize a generator (if used) upstream from the UPS
Expandability
The majority of UPS units on the market is neither modular nor expandable and therefore initial oversizing of the system
is necessary to ensure future expansions (which might not even happen).
Advantages:
- The modular and expandable Trimod® systems allow optimisation of the investments made in UPS units, adapting
them to actual requirements without preventing future expansions and avoiding an unnecessary waste of energy.
- System yield is increased thanks to correct sizing
Reliability
To have a redundancy level with traditional UPS units it is necessary to put at least 2 in parallel, thus doubling the power
bought, the space taken up and the electricity consumed. Instead Trimod®’s modular architecture allows redundant
congurations inside just one single cabinet.
2. Technological description

®
Advantages:
- A UPS with a modular redundant architecture can be congured as an N+X system redundant in power; even in the
case of a failing module the equipment carries on working and there is no stop in work.
- Clear indications and a large display speed up troubleshooting.
- The modular architecture makes short work of repairing a failure by simply replacing the module in question without
interrupting service.
- A high resolution percentage of failures at the rst assistance intervention.
Power module
The basic module, available in three power sizes, 3,400 VA, 5,000 VA and 6,700 VA, is basically made up of the following
functional blocks: command and control logic (microprocessor controlled), rectier/PFCr, inverter, booster, battery
charger, automatic bypass.
The power unit is the Plug & Play type to facilitate power expansion and all maintenance works. Each module is paralleled
with other identical ones until the UPS power is reached.
The power modules are separate from each other and can work even if one malfunctions. A LED on the front of the
module, with a trac-light code, quickly shows the operating state of the electronic unit.
Prescription forms for PM4, PM6 and PM7 only on the related cabinets: UPS Trimod® electrical distribution equipment
is sized for its nominal power and must be used only with power modules originally installed.
Each cabinet must use only the provided power modules, described in table "Mechanical properties" on page 18 of this
manual. It is not possible to use power modules other than those indicated, nor mix with other models and/or replace
the type of modules.
• The model, the power rating and the type of power module to be installed in the UPS cabinet UPS Trimod® are indicated
on the user manual and on the label inside the door of the UPS.
• The type and power rating of the power module are indicated on the label axed to the bottom of the power module
for proper identication.
It is recommended to use only provided UPS Trimod® Power Modules.
Battery drawers
The battery modules are designed for easy insertion in the cabinet with no work needed to connect them; they are easy
to handle thanks to their light weight, likewise any maintenance or replacing.
A box holds 5 12V, 7.2 Ah or 9 Ah batteries connected in series and, thanks to the Plug & Play connection can be easily
pulled out and put inside the cabinet. In order to guarantee maximum safety, especially during maintenance, the voltage
of each box is adequately disconnected into two 24 and 36V branches and restored only when the box is placed right
inside its housing. This conforms to the CEI-EN 60950 standard on electrical safety which establishes that adequate
safeguards must be used and particular attention where there are dangerous voltages higher than 50 Vdc with the
possibility of direct contact.
Autonomy can be increased further still by adding other battery ‘boxes’ in multiples of four,
exploiting the space inside the UPS and the space in the additional ‘modular cabinets
Digital display and displaying alarms
Trimod® is controlled by a microprocessor and has a backlit alphanumerical liquid crystal display (LCD) with 20 characters
on 4 lines built into the front of the UPS where there is also a highly luminous operating status indicator which, by means
of a trac-light code, indicates the operating status and any alarm conditions.
Four simple push buttons near the display allow the user to: see operating data, set operating parameters, analyse the
state of each single power module, select the language in which to see the messages and execute a set of functional tests.
BCM (Battery Charger Module)
It works together with internal PM chargers, with the same intelligent management of the charging cycle. For each BCM
installed the maximum batteries recharging current is increased of 15Adc: 1 BCM has a charging current equivalent to
that of 6 (internal to the charger) PMs. This guarantees to reduce charging time in installations that require long backup
time UPS and increases the availability of the UPS system after a power failure (blackout).
During operation, the module draws current from the phase input (slot) in which it is installed. If at least n°1 PM is present,
it is possible to install any number of BCM.
2. Technological description
Trimod®
Operating and Maintenance Manual
11
All informations about BCM are indicated by LED on the front of the module and described on the display menu.
The module is controlled by a microprocessor to optimize performance and reliability, we recommend the use in
combination with higher than 60Ah capacity batteries.
Input voltage 230V +15% -20%, rated output power 4kW, maximum rated current 15Adc, maintenance voltage 13.75Vdc/
battery. Operating status through the UPS front panel LEDs and multi-colored, adjustable fan speed versus power output,
overtemperature protection.
Intelligent charging cycle with four stages to maximize battery life (constant current, nal charge, maintenance and
stand-by).
O-Line Mode
The UPS Trimod® ® provides a mode of operation o-line that allows to save power while still providing the protection of
the continuity of power supply to the connected load. During the operation O-Line, the load is powered directly by the
mains through the automatic internal bypass circuit in power modules.
This means that the voltage and the output frequency are the same as the network input, and the UPS Trimod can not
control these variables. The benet that you get in the O-Line mode is greater electrical eciency since UPS doesn’t
work. If the output voltage goes out of tolerance range (± 15% of the set voltage output) or is lacking, the UPS activates
its stage inverter powering the load with the energy stored in the batteries.
The runtime during battery operation depends on the conguration of the UPS (full load, battery capacity) and the
percentage of applied load. When AC input is within the parameters of tolerance, the UPS automatically returns to the
O-Line mode. And it is possible to change the operating mode between On-Line and O-Line (and vice versa) when the
UPS is ON or OFF (entering Service Mode).
• To activate the O-Line, enter the Main Menu -> Settings UPS -> Bypass -> O-Line Mode and select Enabled, conrm
the selection with the Enter button.
• To activate the On-Line, enter the Main Menu -> Settings UPS -> Bypass -> O-Line Mode and select Disabled, conrm
the selection with the Enter button.
WARNING!
If the load needs to be fed without any interruption or with a regulated voltage amplitude and/or frequence it is
recommended to use the UPS Trimod® mode On-Line double conversion.
