Emerson user manual Liebert GXT2U Configuration Program Abilities

CONFIGURATION PROGRAM

This is a new feature included with the new Liebert GXT2U line. Several UPS settings that were previously not available or required custom manufacturing may now be modified using this program. For most users, the factory default settings will be adequate. This manual illustrates the features available for modification, as well as the factory default setting.

NOTE

The UPS must be turned off—and not powering connected equipment— before you make any changes to configuration settings.

While the UPS is in Normal Mode operation, press the OFF button once to put the UPS into Bypass Mode.

Once the UPS is in Bypass Mode operation, press and release the OFF button two distinct times (for about a second each time) to turn off the UPS.
