Goodrive30 Series VFD Installation guidelines
-19-
Route the motor cables, input power cables and control cables separately.
DC bus circuits of GD series VFDs cannot be connected in parallel with those of CH series
VFDs.
When DC bus circuits of GD series VFDs are connected in parallel with those of CH series
VFDs, the power of these VFDs must be the same, and power-on and power-off shall be
conducted simultaneously.
For parallel connection of DC bus circuits, current sharing on the input side of the VFD
shall be considered during wiring. It is recommended to configure an equalizing reactor.
3.2.3 Wiring procedure of the main circuit terminals
1. Connect the ground wire of the input power cable to the ground terminal (PE) of the VFD,
connect the 3PH input cable to the terminals R, S, and T, and fasten them up.
2. Connect the grounding wire of the motor cable to the ground terminal of the VFD, and
connect the 3PH motor cable to the terminals U, V, and W, and fasten them up.
3. Connect the braking resistor and other accessories that are equipped with cables to the
specified positions.
4. Fasten all the cables outside of the VFD mechanically, if possible.
