：
▷ Whether the power supply and distribution are normal;
▷ Whether the branch breaker is tripped, and close the breaker after troubleshooting;
▷ Whether the connection is correct, if the cable comes off, should be properly connected to tighten the
cable.
The charger is automatically protected in the event of the fault. The fault information and handling
methods are as follows.
· Check the connection of charging connector and EV
socket.
· Disconnect and reconnect the charging connector.
· Check whether the input cable is reliably connected.
· Check whether the input voltage is abnormal.
·
Check whether the input cable is connected correctly.
· Check whether the input voltage is abnormal.
· Check whether the charging station is covered or installed
in a high temperature environment.
· Power off and restart the device.
·
Check whether the charging connector and its cable are
damaged or wet.
· Recover after pulling out the adapter.
· Check whether the charging adapter and its cables are
damaged or wet.
· Check whether the charging connector is correctly
connected.
