2.2.2.2 Bypass Mode

The UPS automatically transfers to bypass mode upon detecting power module
overtemperature, overload, or other faults that may cause the inverter to shut
down. In bypass mode, loads are powered by the bypass module. The bypass
power supply is not protected by the UPS and therefore is prone to the mains
outage, abnormal AC voltage waveform, or abnormal frequency.
