Operator Control Panel

The control panel and LCD on the front of the Liebert NX lets the operator:

• turn the UPS on or off
• transfer into the various operating modes
• silence alarms
• check the status of the UPS and its batteries, including all measured parameters, events and

alarms

by changing color when ON, flashing or OFF

Liquid Crystal Display (LCD) and Navigation keys - view status and operational data from

the NX in tabular format

Control buttons - turn the NX on or off, silence alarms
