APC DP300E manual Programming of system configuration parameters, 438, 346, 326, 35C/95F

Programming parameters

*Text in bold letters are the factory standard setting

**Advanced Battery Monitor

***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!!

4.3.1 System configuration parameters
