5.2 USB Port Communication

The standard B-type USB port is used to connect the UPS and network server or other computer

system using Liebert MultiLink

A standard B-type USB port is provided to allow connection to a computer or network server. The

USB port can be used to communicate with the Liebert GXT4 configuration program (see section 5.2.1

for details) or Liebert MultiLink (refer to 5.1.1 - Liebert MultiLink for description) that is provided

on the CD that is included with the UPS.

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.

Programming the output voltage of a 230V model of the Liebert GXT4 to 220V automatically

derates the UPS to 96% of both the VA and watt ratings (refer to 9.0 - Specifications for 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.

• A computer running Microsoft

Windows 2000

, Windows XP

, Windows Vista

Windows 7 or Windows 8 is required to set up and run the configuration program.
