Protective grounding terminals, every
machine is provided 2 PE terminals as the
standard configuration. These terminals
should be grounded reliably.

Control power supply terminal
Optional parts (external 220V control
power supply); without powering on input
main circuit, inverter commissioning can be
carried out conveniently and safely by
powering on auxiliary power supply.
Note:
Do not use an asymmetrically constructed motor cable. If there is a symmetrically
constructed grounding conductor in the motor cable in addition to the conductive shield,
connect the grounding conductor to the grounding terminal at the inverter and motor
ends.
Braking resistor, braking unit and DC reactor are optional parts.
Route the motor cable, input power cable and control cables separately.
If the terminal description is
“/”, the machine does not provide the terminal as the
external terminal.
4.3.3 Wiring of terminals in main circuit
1. Fasten the grounding conductor of the input power cable with the grounding terminal of the inverter
(PE) by 360 degree grounding technique. Connect the phase conductors to R, S and T terminals and
fasten.
2. Strip the motor cable and connect the shield to the grounding terminal of the inverter by 360 degree
grounding technique. Connect the phase conductors to U, V and W terminals and fasten.
3. Connect the optional brake resistor with a shielded cable to the designated position by the same
procedures in the previous step.
4. Secure the cables outside the inverter mechanically.
