Liebert PS UPS
Manual
2.4 Computer Connection
Plug the UPS into a 2-pole, 3-wire grounded receptacle. Then connect one
computer-related device into each of the power receptacles supplied on the
back of the UPS.
2.5 Turn On/Off
Press the switch of the UPS continuously for 1 second and the UPS turns into its normal
state (the green light is on and the beeper is off) after it performs a self-diagnosis (the
beeper and the red and green indicator lights are on) for several seconds. At this time,
user may turn on the PC and other loads. Press the switch of the UPS continuously for 1
second to turn off the UPS.
Note: 1. For the convenient maintenance, please turn on the UPS first before turning on the PC and the
other loads, and turn off the UPS after the loads are turned off.
2. At ordinary times, we recommend to keep the UPS on with the battery charging (even if the loads
are turned off), this will help in the convenient maintenance of the battery.
