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.
WARNING
Keor MOD is a category C3 UPS according to the standard EN62040-2.
The UPS is a product for commercial and industrial application in the second environment – installation restrictions or
additional measures may be needed to prevent disturbances.
INDICATION
When the UPS is used for special applications such as life support systems or any other application where a product failure
is likely to cause substantial harm to people, it is mandatory to contact LEGRAND to confirm the possibility of the equip-
ment to meet the requested level of safety, performance, reliability and compliance with applicable laws, regulations and
specifications.
CAUTION
- While maintenance operations are being carried out, “Maintenance work in progress” signs must be affixed in the de-
partment in such a way that they can be easily seen from any access area.
- The connection of the equipment (and of any accessory devices) signs 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.
- 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, warning message or notice, 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.
- 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.
