5.2.6 External battery
The external battery is used to increase the UPS autonomy time during mains failure. It’s
always provided for UPS having rating >30KVA
IMPORTANT
With an external battery, the internal battery isn’t necessary.
The external battery, (consisting of 32 battery blocks maximum, with 6 cells each for 192
cells total), can be installed in three different cabinets:
- AS028 for 38Ah battery blocks
- AS029 for 65Ah battery blocks
- AS182 for 130Ah battery blocks
The battery circuit breaker is installed inside the external battery cabinet, so it’s not
provided in the UPS. Concerning the installation of the external battery cabinet, refer to the
details given in paragraph 5.2.5.
