To cold start a Smart-UPS:
Turn OFF and Unplug the UPS from the wall
Press and HOLD the power button (Test) on the front of the UPS until you hear a long beep
During the long beep, let go of the TEST button. If you waited too long and the beep stopped, you’ll have to do it again
If you let go during the long beep, the UPS should start, go through the self test and run off battery power. The unit will beep to let you know that it’s running on batteries
If you’r testing to see if the wall outlet is working, you can plug the UPS back in to the wall socket, if there is acceptable power, the UPS will switch to normal operation
