Turning the UPS On
After the UPS is connected to a power outlet, it conducts a self-test and
enters Standby mode.
To turn on the UPS, press the On
button on the front panel. The
μ
indicator illuminates solid and the bar graph indicators display the
percentage of load being applied to the UPS.
Starting the UPS on Battery
To turn on the UPS without using utility power, press and hold the
On
button for at least four 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.
