***Viewable only in a parallel configuration.
NOTE:
Common battery pack is a technical possibility. However, APC recommend separate battery pack due to a higher safety degree in con- nection with redundant/parallel operation.
The UPS system is prepared for both solutions.

4.3Programming of system configuration parameters
The system configuration parameters are protected by a password because most of them are critical for correct operation of the system.
Wrong programming can for example destroy the battery or cause loss of output voltage during operation!!
