Back-up the load data before conducting the check.
1. Press the power button to check the indicators and display function.

3. Make sure that there are no audible or silenced alarms.
4. Select the Setting menu, and look at the log for alarm and fault history.
5. Check the operating mode for Normalmode. If the UPS is operating in Bypass mode, contact
Vertiv Technical Support.

normal. If so, contact Vertiv Technical Support.
