2.5 Signs on the equipment
Displayed on the UPS are explanatory plates that can vary depending on the country the equipment is intended for and
constructional standards applied.
Make sure the instructions are adhered to. Removing these plates and working in a way that differs from what is written
there is strictly prohibited.
The plates must always be clearly read and they must be cleaned periodically.
If a plate deteriorates and/or it is no longer legible, even partially, the Manufacturer must be contacted for a replacement.
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 that are
considered indispensable. Always operate with due care around dangerous areas marked by the appropriate warning
notices on the equipment.
2.6 General warnings
DANGER
The UPS works with dangerous voltages. SKILLED TECHNICIANS shall 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 direct current energy source (batteries). The output terminals may have a dangerous
voltage even if the UPS is not connected to the power network in alternate current.
Disconnect all external battery units before performing any installation and/or maintenance operation.
