5.2.1 Configuration Program
The configuration program is on the Liebert GXT4 CD and can be used instead of making
configuration setting changes from the LCD panel. The configuration program communicates to a
computer running a Microsoft
®
Windows
®
operating system via the included USB cable.
For most users, the factory default settings are adequate. This section give a brief overview of the
features and parameters that are available for modification, as well as the factory default settings.
Should any changes be necessary, refer to the Configuration Program User Manual that is located on
the included CD for further details.
The configuration program allows these features of the Liebert GXT4 to be changed:
• Change and set the display language
• Enable/Disable Auto-Restart (default is Enable)
• Select frequency converter operation with a fixed output frequency of 50Hz or 60Hz, bypass
disabled (default is Auto-Select with bypass enabled)
• Set the Low Battery Warning alarm time from 2 to 30 minutes (default is 2 minutes)
• Enable/Disable the Auto-Battery test (default is Enable)
• Enable/Disable Auto-Restart after removing Remote shutdown (default is Disable)
• Set the wiring mode of Remote shutdown (default is normally open)
• Set the Auto-Enable output after remote shutdown (default is Disable)
• Set the Auto-Battery test to 8, 12, 16, 20, or 26 weeks (default is 8 weeks)
• Select the number of external battery cabinets connected to the UPS to adjust the remaining run
time calculated by Emerson
®
software products (default is zero)
• Select one of multiple output voltages to match various voltages (see Table 8).
NOTICE
The output voltage settings cannot be changed while the UPS is On and powering connected
loads.

NOTE
• Setting the output voltage of the Liebert GXT4-500RT120, GXT4-700RT120, and
GXT4-1000RT120 models to 110VAC automatically derates both the VA and Watt ratings to
95% of the unit’s rating.
• Setting the output voltage of the Liebert GXT4-1500RT120 and GXT4-2000RT120 models to
110VAC automatically derates both the VA and Watt ratings to 85% of the unit’s ratings,
and programming the output voltage to 115VAC automatically derates both the VA and
Watt ratings to 95% of the unit’s rating.
• Setting the output voltage of the Liebert GXT4-3000RT120 model to 110VAC automatically
derates both the VA and Watt ratings to 90% of the unit’s ratings (refer to 9.0 -
Specifications for the VA and Watt ratings).
NOTE
• This program is compatible with UPS models beginning with ‘GXT4,’ as in
‘GXT4-3000RT230.’ It is not compatible with earlier versions of the Liebert GXT UPS.
