The Liebert matching battery cabinet allows installing an optional Alber battery monitoring system in the
cabinet. Alber battery monitoring continuously checks all critical battery parameters, such as cell voltage, overall
string voltage, current and temperature. Automatic periodic tests of internal resistance of each battery will verify
the battery’s operating integrity. Additional capabilities include automatic internal DC resistance tests and trend
analysis providing the ability to analyze performance and aid in troubleshooting.
The Alber monitoring system is installed inside the battery cabinet (see Figure 52 ). The monitoring system is
supplied by an internal transformer.
The transformer is powered from the output of the UPS the battery cabinet is supplying (see Figure 52 ).
The Alber monitoring system consists of a Control Module and a Battery Module (see Figure 50 ). One Control
Module can monitor up to eight battery cabinets with a Battery Module installed. The battery cabinet with the
Control Module (Battery Cabinet #1) must be installed in the position closest to the UPS.
For details about operating the Alber system, see the Alber Monitoring System manual, available at the Liebert

For systems that do not use Liebert battery cabinets, an optional temperature sensor can be installed to monitor
the ambient room temperature. This sensor is connected to the BIB board (see
Figure 17 ). This sensor will allow
the Liebert UPS to perform temperature compensation charging.
