respectively, the UPS can work normally.
If BMD port is disconnected, the UPS will turn to bypass power supply, and at the same
time, the LCD shows BMD fault. Once the port recovers short connection, the fault will
be removed automatically.

completely and short connect the EPO port, the fault will be removed automatically.
