ATTERY MAINTENANCE
CAUTION: DANGEROUS VOLTAGE INSIDE!
Never open the BU for any reason, if any anomaly is detected, contact your local service agent.
Batteries, in order to maintain a high efficiency and durability must be regularly charged using the Modular UPS System itself.
Batteries are subject to self-discharge. In the case where a BU or a Battery Box are stored and not immediately installed, an
appropriate recharge must be planned.
To recharge the batteries, simply connect the Battery Cabinet/Battery Box to a Modular UPS System in “NORMAL OPERATION”
for at least 24 hours.
For long storage periods, contact your local service agent.
