To test new batteries:

1. Plug the UPS into a power outlet for 48 hours to charge the batteries.

2. Press the

(Output On) button on the UPS front panel for at least one second.

3. Verify that the

(Power On) indicator is illuminated, indicating that the UPS is

operating normally and any loads are powered.

The UPS should be in Normal mode.

(Output On) button for half a second to initiate the battery test.

If the UPS is in Normal mode with no active alarms and the bypass voltage is

During the battery test, the UPS transfers to Battery mode and discharges the batteries

for 25 seconds under the existing load. The

(On Battery) indicator illuminates.
