18 - 140 Installation Guidelines
3.2.3 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 L1 , L2 and L3 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.
