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 UPS 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 units. Disconnect all
battery drawers and external battery units 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).
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.
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 UPS 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.
12
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 electr ic 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
The equipment generates, uses and can radiate radio frequency energy. If it is not installed and used in accordance with
the instructions, it may cause harmful interference with radio communications.
Trimod HE 10 is a category C2 product according to standard EN62040-2.
In the home environment it could cause radio interference; in this case appropriate countermeasures must be taken.
All other Trimod HE models are category C3 products according to standard EN62040-2.
They can therefore be used in commercial and industrial environments; nevertheless restrictions or adequate
countermeasures might be necessary to avoid radio interference.
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
with T31 material, installed as close as possible to the clamps;
- pass the input cables through three EPCOS TDK toroids code B64290L699X35 made with T35 material;
- pass the output cables through two EPCOS TDK toroids code B64290L699X35 made with T35 material;
CAUTION
- The equipment must be maintained and used according to the instructions written in the manuals.
- The departmental manager must instruct the operating and maintenance personnel on the safe use and maintenance
of the equipment.
- Only specifically-trained, highly skilled personnel are allowed access to the equipment in order to per form maintenance.
While the maintenance operation is being carried out, signs saying "Maintenance work in progress" must be affixed in
the department in such a way that they can be easily seen from any access area.
- The connection of the equipment (and of any accessory devices) must always be perfectly grounded to discharge short-
circuit currents and electrostatic voltages. The input voltage must correspond with the value shown on the rating plate.
Current adapters must not be used under any circumstances. Pay attention to polarity when connecting.
- Any intervention on the equipment must be done only after it has been disconnected from the power supply network
by means of a switch disconnector and must be locked with an appropriate padlock.
- The UPS must not be turned on if liquid is leaking from the batteries.
- The equipment used for any maintenance operations (pliers,screwdrivers etc.) must be electrically insulated.
- Depositing flammable material near the equipment is strictly forbidden. The equipment should always be locked, and
only specifically trained personnel are allowed access to it.
- Do not disable any safety notification or warning device and do not ignore any alarm or warning message no matter
whether they are generated automatically or represented by plates fixed to the equipment.
- Do not run the equipment with fixed protections not installed (panels etc.).
- In case of breaking, buckling or malfunctioning of the equipment or parts of it, repair or replace immediately.
- For no reason can the structure of the equipment, the devices mounted on it, the operation sequence etc, be modified,
manipulated or tampered with in any way, without prior consultation with the Manufacturer.
- When replacing fuses, only use ones of the same type.
- The replacement of the batteries is an operation intended to be carried out by a skilled technician.
- Keep a register in which to enter the date, time, type, performer’s name and any other useful information about each
and any routine and extraordinary maintenance operation.
- Do not use oils or chemical products for cleaning because they could scratch, corrode or damage certain parts of the
equipment.
- The equipment and workplace must be kept completely clean.
- Upon completion of the maintenance operations, before connecting the power supply, carefully check that no tools
and/or material of any kind have been left next to the equipment.
