6.1 Installation
The operator (paragraph 2.2.2) is not authorized to install and connect electrically the UPS. These operations are the sole
preserve of a skilled technician (paragraph 2.2.1) who must follow the instructions addressed to him in the installation
and maintenance manual.

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.

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
overheating.

The periodical checks involve operations inside the UPS in presence of dangerous voltages. Only maintenance personnel
trained by LEGRAND are authorized to intervene.
6.4 Ordinary maintenance
Contact a skilled technician if it is necessary to replace or add power modules, battery drawers or external battery cabinets.
