What to do if Liebert PowerSure Personal XT 700 has green LED off, red LED on, and continuous beeps?
If the green LED is off, the red LED is lit, and you hear continuous beeps from your Liebert UPS, it could be due to an output short circuit or an overload exceeding 120%. In the first case, remove all of the equipment. In the second case, reduce the load on the UPS.
Why does my Liebert PowerSure Personal XT 700 UPS beep with green LED on and red LED blinking?
If the green LED lights up, the red LED blinks, and you hear one beep every half-second from your Liebert UPS, it means the power demand from the connected equipment is too high. To resolve this, remove some equipment until the UPS stops beeping.
