After overloading, the UPS powers the loads and a hurried alarm will sound (1s on/1s off). By reducing the load
within the 100% threshold, the UPS returns to normal operating mode.
When the overload level is too high, the overload protection is activated and the UPS will be completely
shutdown.
To restore normal operation following failure due to overloading (continuous beep and load not powered), reduce
the load so that it falls within the 100% 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.
