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. The
bypass power supply is not protected by the UPS which means it may be affected by mains
outage, and incorrect AC voltage or frequency.
