Liebert Complete Guide to Configuring Your GXT2 UPS

Configuration Program

7.0CONFIGURATION PROGRAM

The final step of installation may require custom configuration of your UPS using the enclosed config- uration program. Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put into full-time service powering the critical load.

For most users operating with 230VAC and with no external batteries, the factory default settings will be adequate.
