Emerson GXT2U User Manual

ONFIGURATION

ROGRAM

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.

Liebert GXT2U Configuration Program Abilities

• Select one of five output voltages to match voltages found around the world.
• Enable/Disable Auto-Restart.
• Select frequency converter operation with a fixed output frequency of 50 or

60 Hz.

• Set the Low Battery Warning alarm time from 2 to 30 minutes.
• Enable/Disable the Auto-Battery test.
• 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 calculations reported by Liebert software

products.

• Modify the shutdown setting of DB-9 pin 6 (for information on pin assign-

ments, see Communications on page 19).

What You Will Need

In addition to the Liebert GXT2U UPS, you will need the configuration program

diskette and serial cable (beige or tan, 3-wire: GND, TX, RX; straight through 2-

2, 3-3, 5-5) included in the UPS accessory box. The BLACK ML9P9S CONTACT

CLOSURE communication cable IS NOT compatible with the configuration

program. A Windows 95

, 98

, or NT

computer—desktop or laptop—is also

required to set up and run the configuration program.

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.

NOTE
This program is compatible with UPS models beginning with

“GXT2-”, as in “GXT2-2700RT208.” It is not compatible with earlier

versions of the Liebert GXT UPS.
