After switching over to the bypass due to overloading, the UPS powers the loads off mains power and a
continuous alarm will sound. By reducing the load within the 102% threshold, the UPS returns to normal
operating mode.
When the overload level is too high, the input thermal protection is activated and the UPS will be completely
shutdown.
To restore normal operation, reduce the load so that it is within the 102% threshold and restore thermal
protection by pressing the relevant button on the rear of the UPS and then switch on again.
To restore normal operation following failure due to overloading (continuous beep and load not powered),
reduce the load so that it falls within the 102% threshold. Hold the OFF button down until the continuous beep
stops and then release it. Wait until the UPS is completely shutdown and then switch on again.
