Automatic Self-
Test
The UPS performs a self-test automatically when turned on, and every two
weeks thereafter (by default).
During the self-test, the UPS briefly operates the connected equipment on bat-
tery.
If the UPS fails the self-test, the replace battery LED
illuminates and im-
mediately returns to online operation. The connected equipment is not affected
by a failed test. Recharge the battery for 24 hours and perform another self-test.
If it fails, the battery must be replaced.
Manual Self-Test
Press and hold the button for a few seconds to initiate the self-test.
