5.2USB Port Communication

The standard B-type USB port is used to connect the UPS and network server or other computer system using Liebert MultiLink®. The configuration program can be completed through the communication port.

5.2.1Configuration Program

Accessing the Configuration Program via USB is a new feature of the Liebert GXT3. For most users, the factory default settings will be adequate. This section illustrates the features available for modification, as well as the factory default setting.

The USB configuration program allows these features of the Liebert GXT3 to be changed:

•Enable/Disable Auto-Restart

•Select frequency converter operation with a fixed output frequency of 50Hz or 60Hz, bypass disabled

•Set the Low Battery Warning alarm time from 2 to 30 minutes

•Enable/Disable the Auto-Battery test

•Enable/Disable Auto-Restart after removing Remote shutdown

•Set the wiring mode of Remote shutdown

•Set the Auto-Enable output

•Set the Auto-Battery test to 7, 14, 21 or 28 days

•Select the number of external battery cabinets connected to the UPS to adjust the remaining run time calculated by Emerson® software products

•Select one of multiple output voltages to match various voltages (see Table 6).

NOTICE

The output voltage settings cannot be changed while the UPS is On and powering connected loads.

NOTE

Programming the output voltage of a 230V model of the Liebert GXT3 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 ‘GXT3,’ as in ‘GXT3-3000RT230.’ It is not compatible with earlier versions of the Liebert GXT UPS.

•A computer running Windows 2000®, XP® or Vista® is required to set up and run the configuration program.
