Note:

It is not recommended to use asymmetrical motor cables. If there is a symmetrical
grounding conductor in the motor cable besides the conductive shielded layer, ground
the grounding conductor on the VFD end and motor end.

Braking resistor, braking unit and DC reactor are optional parts.

Route the motor cable, input power cable and control cable separately.

GD series VFDs cannot share the DC bus with CH series VFDs.

When sharing the DC bus, the VFDs must be the same in power and must be
simultaneously powered on or off.

In shared DC bus running mode, current balance on the VFD input side must be
considered during wiring, and equalizing reactors are recommended to be configured.
4.3.3 Wiring procedure of main circuit terminals
1. Connect the grounding line of the input power cable to the grounding terminal (PE) of
the VFD, and connect the 3PH input cable to R, S and T terminals and tighten up.
2. Connect the ground wire of the motor cable to the PE terminal of the VFD, connect the
motor 3PH cable to the U, V and W terminals, and tighten up.
3. Connect optional parts such as the braking resistor that carries cables to designated
positions.
4. Fix all the cables outside the VFD mechanically if allowed.
