•
Connect the shield at both ends at the motor and at the converter.
•
Keep unshielded cable ends as short as possible.
•
Establish the connection through a larger surface area so that high-frequency currents are
suitably discharged. Establish a 360° connection at the converter and at the motor, for
instance using EMC cable glands at the cable entries.
