8.0 CONFIGURATION PROGRAM
The configuration program included with the Liebert GXT2U line
allows modification of several UPS settings that were previously
unavailable or required custom manufacturing. The user manual on
the configuration program disk describes the features available for
modification, as well as default settings.
8.1 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
assignments, see 7.0 - Communications).
8.1.1 What You Will Need
Using this program requires a computer
running Windows (95 through Server
2003), as well as the configuration program disk and serial cable
included in the UPS accessory box. Use the serial cable (beige or tan,
3-wire: GND, TX, RX; straight through 2-2, 3-3, 5-5) to connect the
computer to the Liebert GXT2U UPS.
Note: The black ML9P9S contact closure communication cable is NOT
compatible with the configuration program.
NOTE
The UPS must be turned off—and not powering connected equip-
ment—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 “GXT2-1500RT120.” It is not compatible with
earlier versions of Liebert GXT UPS.
