Operation

2.0OPERATION

The Liebert NX UPS is equipped with a microprocessor-based display touchscreen designed for convenient and reliable operation. The display is driven by menu-prompted software.

2.1Features

The Liebert NX 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 event files

•Adjustment programmable parameters

The touchscreen display has a blue-background and multicolored text. The display turns On automatically, but dims and the backlight goes out after 15 minutes of inactivity. Touching the screen will reactivate the backlight 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.
