Note:
1. Do not use asymmetrical motor cable. If there is a symmetrical grounding conductor in the
motor cable besides the conductive shielded layer, ground the grounding conductor on the
inverter end and motor end.
2. Brake resistor, brake unit and DC reactor are optional parts.
3. Route the motor cable, input power cable and control cables separately.
4. "None" means this terminal is not for external connection.
5. HD2IP series inverters cannot share the DC bus with any other inverters.
6. When sharing the DC bus, the inverters must be the same in power and must be
simultaneously powered on or off.
7. In shared DC bus running mode, current balance on the inverter input side must be
considered during wiring, and equalizing reactors are recommended to be configured.

4.3.3 Wiring process of the main circuit terminals

1. Connect the grounding line of the input power cable to the grounding terminal (PE) of the
inverter, 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 inverter,
and connect 3PH motor cable to U, V and W terminals and tighten up.
3. Connect the brake resistor which carries cables to the designated position.
4. Fix all the cables outside the inverter mechanically if allowed.
