2.2.2.2 Bypass Mode

The UPS automatically switches to bypass mode when it detects power module
overtemperature, overload, or other faults that may cause inverter shutdown. 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.
