3.2.4 Input Power Failure( LoadOn Battery)

Ifthe utility AC power source fails, or is outside the acceptablerange, the battery plant becomes the power

sourcefor the UPS module inverters. The UPS system continues to supplypower to the critical load, and also to

thecontrols of the UPS modules and the SCC.

Youcan use the Battery Timescreen at the UPS modules to monitor thepresent battery voltage compared to the

shutdownvalue. The length of time the battery can sustain the load dependson the size of the load and the size

andcondition of the battery plant. The battery plant is usually largeenough to supply a 100% rated load for 15

minutes.

Alarmmessages that indicate battery status are Battery Discharge,Low Battery, and Battery Shutdown. The

voltagelimits for these alarmsare displayed on the UPS module Alarm LimitSettings screen. These limits were

selectedfor your installation by Liebert Global Servicesduring initial start-up.

Thebattery block in the UPS module Monitor/Mimic Display indicatesCharge or Discharge and the current in

Amperes.Maximum battery discharge current ranges from 324 amps (for 150 kVA)to 1620 amps (for 750

kVA).Refer to the separate InstallationManual or drawings for specific data on your system.
