Never open the BU for any reason, if any anomaly is noted, contact the assistance service.
Batteries, in order to maintain a high efficiency and durability must be regularly charged using the HIMOD HP UPS System itself.
Batteries are subject to the self-discharge phenomenon. In the case where BU or Battery Box are stored and not immediately
installed, an appropriate recharge must be planned.
To recharge the batteries, just connect the Battery Cabinet/Battery Box to a HIMOD HP System in “NORMAL OPERATION” for
at least 24 hours.
For long storage periods, contact the assistance service.
