4.7 Overview of power supply, grounding and motor cable
• Power should be connected to the L1/L and L2/N terminals for single phase drives, L1, L2 and
L3 for three phase drives. Phase sequence is not important.
• For EMC compliance Class C1, a symmetrical shielded cable is recommended.
• All cables should be dimensioned according to any local codes or regulations.
• Motor cable must be a symmetrical shielded cable where the screen covers at least 85% of the
cable surface area to fulfil EMC requirements. Example of cables to be used are RKFK, Ölflex
Classic 100 CY, FKKJ-EMC, or similar.
• Protective grounding of motor is connected to drive
• Motor cable should be connected to U, V, W.
• Motor is to either be connected in Star or Delta
➢ Inverter Power supply 3*400 VAC:
- Rated voltage of motor 230/400, Star connection
- Rated voltage of motor 400/660, Delta connection
