6.8.3 Shield connection
Only use shielded medium-voltage cables to reduce cable-conducted radio frequency
interference (RFI) and to achieve the appropriate EMC compatibility.
● The cable shield must be uninterrupted over the complete length of the cable and must
comprise non-magnetic material. Preferably use cables with foil-type shields.
● Do not connect other cable shields, power cables or control signals to the motor cable
shield. Powerful electrical interference and disturbances are induced in cables such as
these.
