A.4 Requirements on Cables and Cabling
A.4.1 Requirements for Shielded Cable
1) Use the shielded cable to connect the motor to meet the EMC requirements. The
4-conductor shielded cable is recommended with one conductor as the PE. If the
3-conductor shielded cable is used and the shield cannot meet the conduction
requirements, an additional PE wire must be added.

3) The grounding area of the shielded cable must be as large as possible. Fasten the
shield to the metal plate with the metal cable clamp, as shown in the following
