Attention : If the power specification of the control box is AC 220V, please
don’t connect to AC 380V power outlet. Otherwise, error code
will appear. In this case, please turn off the power
switch immediately and check the power voltage. Continuous
supply of 380V over 5 minutes might damage the PCB,
endangering the safety of users.

properly (including machine, motor, control box).
Single phase (AC220V)
b. The grounding wire of the power cord should be connected to the system ground wire of the
production factory with conducting wire of appropriate size and connector and this connection
should be permanently fixed.
