▲ It is recommended to adopt thick cable with demanded diameter no smaller then in the
attached form. Grounding wire should be near inverter, and ground wire be as short as
possible.
▲ When the motor is grounded on inverter side, please use one core of the four-core cable
to ground, with the same size to input wire.
