10.4Checking UPS Status

Emerson® recommends checking the UPS operation status every six months.

•Check whether the UPS is faulty: Is the Fault Indicator on? Is the UPS sounding an alarm?

•Check whether the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal Mode. If it is operating in Bypass Mode, stop and contact your local Emerson representative, or Emerson Channel Support.

•Check whether the battery is discharging. When the mains input is normal, the battery should not discharge. If the UPS is operating in Battery Mode, stop and contact your local Emerson representative or Emerson Channel Support.
