After the UPS is connected to a power outlet, the UPS enters Standby
mode. To turn on the UPS, press and hold the
button until you hear
the UPS beep (approximately two seconds). After the UPS is turned on, it
conducts a self-test and enters Normal mode. The

indicator
illuminates indicating that power is available from the UPS output
receptacles.
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
button for two seconds. The UPS supplies power to your equipment
and goes into Battery mode. When the UPS starts on battery, it does not
conduct a self-test to conserve battery power.
Turning the UPS Off
To turn off the UPS, press and hold the button for two seconds and
then unplug the UPS from the power outlet. If you do not unplug the
UPS, it remains in S tandby mode.
