Liebert NXL UPS

2 OPERATION

The Liebert NXL UPS is equipped with a microprocessor-based display touchscreen
designed for convenient and reliable operation. The display is driven by an easy-to-
follow, menu-prompted software.

2.1 Features

The Liebert NXL interface display enables the operator to perform such tasks
as:
• Quickly check operational status
• Monitor the power flow through the UPS system and all meter readings
• Execute operational procedures
• Check status reports and history files
• Adjustment programmable parameters (access limited by security access
function)
• Adjustment output voltage before performing a manual load transfer.
The touch screen is a white-background display with multicolor text. The display
turns on automatically, but after 15 minutes of inactivity the backlight will go out and
the display will appear very dim.
Touching the screen will reactivate the backlight; the backlight will again be active for
15 minutes. If any screen other than the mimic screen is accessed, that screen will be
displayed for 5 minutes without any interaction. If there is no activity for 5 minutes,
the display will revert to the basic mimic screen.
