Backup time

This operation may be carried out only by qualified electricians using the necessary safety equipment for work on live parts
(insulated tools, gloves, goggles).

The connection of each module to the electrical supply must be protected by an easily accessible circuit
breaker (not supplied). A module can be isolated from the electrical supply by opening this circuit
breaker.

Before making any connections or working on the equipment, make sure the battery circuit breaker is in OFF
position and that the main contacts of the upstream protective devices of the electrical installation are open (OFF
position)

.

For maximum battery life, CLA and UPS modules must be installed in the same room as batteries so that the automatic
regulation of the charge voltage as a function of temperature can work correctly.
