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.

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
