Battery Monitoring System—Optional
The matching Liebert battery cabinets allow installing an optional Alber BDSUi battery
monitoring system inside the cabinet. The Alber BDSUi 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 BDSUi system is installed inside the battery cabinet as shown in
monitoring system power inlet is wired to the Alber BDSUi fuse block on the UPS (see
and
). The Alber BDSUi fuse block supplies 120VAC and has an 8A fuse.
If required, power can be supplied from the output terminals of the UPS, a distribution panel or
another UPS-protected source.
For details about operating the Alber system, refer to the Alber unit’s documentation, available at
