Safety protection grounding terminal
Grounding terminal for safety
protection. Each VFD carries
two PE terminals and proper
grounding is required.

For 660V models:
220V control power
supply terminals
Terminals for connection to
external 220V power supply.
Note:
Do not 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 cables separately.
"Not available" means this terminal is not provided for external connection.
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.
4.3.4 Wiring procedure of the 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 grounding line of the motor cable to the grounding terminal of the VFD, and connect
3PH motor cable to U, V and W terminals and tighten up.
3.
Connect the braking resistor which carries cables to the designated position.
