UPS Tab

When the program starts, the following window will open displaying the UPS model along with the

current UPS settings. This information can be refreshed at any time using the REFRESH button.

These illustrations show the factory default settings for 120VAC UPS at the left, and output L-N volt-

ages available to select at the right.

8.6.1

The Output Voltage displayed is the nominal input/output voltage. This is not a voltmeter and will

display the nominal voltage whether the UPS is On or Off. The drop down box will show the alternate

L-N voltages available. Select the voltage that matches the nominal utility in your location.

Output Voltage Selection Notes

For the Liebert GXT2 dual inverter models, this sets the L1-N and the L2-N nominal voltage. The

L1-L2 voltage depends upon the phase angle of the input utility and is auto-detected when power is

first applied.

For the Liebert GXT2 230V single inverter model, only those voltages supported by the UPS will be

displayed.

L-N Reverse Detection—120V UPS Models Only

Proper wiring of the receptacle powering the UPS is critical for safety, EMI suppression, and surge

suppression. The UPS checks the outlet when first plugged in. If the Line-Neutral is reversed or the

ground is missing, the UPS will not start. If a problem is detected after the UPS is started, the UPS

will continue to operate, but the AC INPUT LED will flash. In some unique applications the user may

wish to disable this alarm. Except for special situations, improperly wired receptacles should be

immediately repaired before the UPS is put into service. Click on the box to remove the check mark

and disable this alarm.
