Rack-Mounting Battery Packs - Huawei ESS-240V12-9AhBPVBA Series Quick Installation Manual

Rack-mounting Battery Packs

1. A UPS2000-G-6 kVA/10 kVA requires one battery pack to provide standard backup time, and
requires two to four battery packs to provide long backup time. For a UPS that provides long
backup time, battery packs connect to each other in parallel and then connect to the UPS battery
input port. The following figure shows how to connect four battery packs in parallel.
2. If the number of UPS2000-G-6 kVA/10 kVA parallel system is greater than or equal to 3, each
UPS can be configured with one to four battery packs. The installation methods for each UPS and
battery pack in the parallel system are the same as those in a single UPS system. The installation
sequence is: UPS > battery pack > UPS > battery pack ... UPS > battery pack.
