PE
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 and braking unit are optional parts.
 Route the motor cable, input power cable and control cables separately.
 If the terminal is not appeared, 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.

Protective grounding terminals: every machine is
provided with 2 PE terminals as the standard
configuration. These terminals should be grounded with
proper techniques.
