Communication

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®. Configuration program can be accessed 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 dis- abled

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 Liebert 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

For all 120V models, when the output voltage is programmed for 110VAC, the UPS will be automatically derated as follows (refer to 9.0 - Specifications for VA and watt ratings):

500VA - 1000VA: derated to 95% of both the VA and Watt ratings

1500VA - 3000VA: derated to 90% of both the VA and Watt ratings

NOTE

• This program is compatible with UPS models beginning with ‘GXT3’, as in ‘GXT3- 3000RT120.’ 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.
