Turning the UPS On
After the UPS is connected to a power outlet, the UPS enters Standby mode.
To turn on the UPS, press and hold the (On/Off) button until you hear the UPS beep.
After the UPS is turned on, it conducts a self‐test and enters Normal mode. The

(Power On) indicator illuminates green indicating that power is available to your
equipment.
Starting the UPS on Battery
NOTE: The UPS does not auto-detect the input frequency when starting on battery; the
default is the last frequency used by the UPS.
To turn on the UPS without using utility power, press and hold the (On/Off) button
for two seconds. The UPS starts up in Battery mode and supplies battery power to your
equipment. When the UPS starts on battery, it does not conduct a self‐test to conserve
battery power.
