front panel indicators turn on and cycle through several times.
The

For 208V-240V models, confirm the correct UPS output voltage
is selected (see Steps 3 through 8 on page 40).

Press and hold the Output On button until you hear the UPS

Turn the Bypass switch on the PPDM to the NORMAL position.
The front panel displays the percentage of full load being
applied to the UPS. The UPS is now in Normal mode with the
load online.
