Operation

3.3.4Input Power Failure—Load on Battery

If the utility AC power source fails or is outside the acceptable range, the battery plant becomes the power source for the UPS module inverters. The UPS system continues to supply power to the critical load and also to the UPS controls.

You can use the Battery Time screen at the UPS modules to monitor the present battery voltage com- pared to the shutdown value. The length of time the battery can sustain the load depends on the size of the load and the size and condition of the battery plant. The battery plant is typically large enough to supply a 100% rated load for 10-15 minutes.

Alarm messages that indicate battery status are Battery Discharge, Low Battery and Battery Shut- down. The voltage limits for these alarms are displayed on the UPS module Alarm Limit Settings screen. These limits were selected for your installation by Liebert Global Services during initial start- up.

The battery block in the UPS module Monitor/Mimic Display indicates Charge or Discharge and the current in Amperes. Maximum battery discharge current ranges from 326 amps (for 150kVA) to 1619 amps (for 750kVA). Refer to the separate Installation Manual or drawings for specific data on your system.
