Battery connections
BATTERY CABINET if present:
For connection to the UPS, the battery cabinet must have an overcurrent protection device and a
disconnecting device. This disconnector
must be closed only when the UPS is started up regularly. During
connection to the UPS the disconnector must stay in the open position.
CABINET DISCONNECTOR
For systems with more battery cabinets, use a Battery switch cabinet where the cables can be parallel-
connected (refer to the marketing department). For the sizing of the cables and connection procedures, refer
to the “INSTALLATION DRAWING” attached to the battery cabinet.
For back-up times requiring a greater number of Battery cabinets, contact the marketing department.
