7A. Maintenance
Clean the UPS with a dry cloth after turning off all power to the UPS and switching off the power
switch.
The UPS performs monthly automatic battery tests. However, it is recommended that a 6 month test
be performed on the UPS for battery condition. Perform all tests off peak hours with applications
shut down.
1. Turn off power to the UPS via the branch circuit breaker to the UPS. It is not recommended
to disconnect the plug from the UPS to the utility power due to disconnection of the safety
ground.
2. Allow the UPS to run on battery power for 1 minute. Monitor the UPS for any fault LEDs and
if none are observed, return power to UPS and log results below in the maintenance log. If
battery fault LED is lit, call for service.
