Emerson 480V ユーザーズマニュアル

The Liebert matching battery cabinet allows installing an optional Alber Battery monitoring system 

in the cabinet. The Alber Battery Monitoring by Liebert 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 10). The monitoring 

system requires approximately 0.5A, single-phase 480V.

This power can come from the output terminals of the UPS, a distribution panel, or another 

UPS-protected source. This power is to be field supplied. See Figure 30 for wiring location.
For details about operating the Alber system, see the Alber Monitoring System manual.

NOTE
This power must be UPS protected.
