6.9.1. Operation of changing battery numbers through LCD menu
By default, the Balder 6000 UPS is set to operate with 2U battery cabinet
that contains 16 batteries of type 12V7Ah or 12V9AH (12V x 16 = 192V).
By default, Balder 10000 UPS is set to operate with 3U battery cabinet that
contains 20 batteries (12V x 20 = 240V).
However, for each of these models it is possible to set a different number
of batteries present in the attached cabinets (16 to 20 batteries, only for 3U
battery cabinet). To do this, you need to access a hidden settings menu, which
requires a password. Described below is how to set the number of batteries.
WARNING!
If you need to change the battery number this should be done before you connect
the battery cabinet to the UPS. After you set the battery number and completely
turn off the UPS, you can connect the battery cabinet to the UPS.
