6.5 Checking UPS Functions

Emerson recommends checking the UPS functions once every six months.

Back up the load data before conducting the UPS functions check. Procedures are as follows:

1. Press the Standby/Manual Bypass button to check whether the buzzer and indicators are normal.

2. Press the On/Alarm Silence/Manual Battery Test button to check again whether the indicators

are on and the UPS is operating normally.

3. Press the On/Alarm Silence/Manual Battery Test button for three seconds after Inverter Mode.

The UPS should initiate a battery self-test. Check to determine whether the battery is operating

normally. If not, stop and contact your local Emerson representative or Emerson Channel Support

NOTE

UPS function check procedures may interrupt power supply to the connected load.
