INSTALLATION and ORDINARY MAINTENANCE operations must be carried out only by SKILLED TECHNICIANS (par-
agraph 2.2.1).
EXTRAORDINARY MAINTENANCE operations must be carried out only by LEGRAND TECHNICAL SUPPORT SER-
VICE.

6.1 Preventive maintenance
The UPS does not contain parts for preventative maintenance by the operator.
The operator must regularly perform:
- a general external cleaning;
- a check to verify there is no alarm indication on the display;
- a check to verify the correct functioning of the ventilating fans on each power module.
6.2 Periodical checks
The correct functioning of the UPS must be guaranteed by periodical maintenance inspections. These are essential to
safeguard the reliability of the equipment.
These inspections should also be made to determine if components, wiring, and connections exhibit evidence of over-
heating.
During a maintenance inspection, the skilled technician must carry out the following checks:
- no alarm presence;
- list of the memorised events;
- correct function of the static and maintenance bypass;
- integrity of the electrical installation;
- flow of cold air;
- battery status;
- characteristics of the applied load;
- conditions of the installation location.
Contact the LEGRAND Technical Support Service in case of problems.
WARNING
The periodical checks involve operations inside the UPS in presence of dangerous voltages. Only maintenance personnel
trained by LEGRAND are authorized to intervene.
