b) it is important to enter the value in Ah, so that the control system calculates
the available backup time and shows it without further changes on the LCd
monitor.
The settings values are determined as follows:
Devices with backup time are configured for internal batteries and external
battery modules. The battery capacity of both are described in Tab. 8
and Tab. 9. for example, a KESSUPS 1500 and a backup extension module
KESSUPS-EbM-36V: 9 Ah + 18 Ah = 27 Ah (value for parameter 12).
