6.2 Low Voltage Disconnection Protection

Principles
If an AC input is abnormal, batteries start to power loads. In this case, the SMU01C drives
contactors to disconnect loads and batteries in sequence based on preset disconnection
parameters. After the AC input resumes, the rectifiers begin to power loads and charge
batteries.
