4.1.10 How to connect the motor - foreword
See section General Specifications for correct dimensioning of motor cable cross-section and length.
• Use a shielded/armored motor cable to comply with EMC emission specifications (or install the cable in a metal conduit).
• Keep the motor cable as short as possible to reduce the noise level and leakage currents.
• Connect the motor cable shield/armor to both the decoupling plate of the adjustable frequency drive and to the metal of the motor. (The same
applies to both ends of the metal conduit if used instead of a shield.)
