Supply system cable
(unshielded)
Signal cable
and bus cable
(shielded)
Encoder cable
(shielded)
Minimum distance between power cables and signal cables: 20 cm to 30 cm
Shield bonding of the motor cable in the converter on an EMC shield busbar using EMC shield
clips and connection of the three symmetrical PE conductors on the PE busbar
Shield bonding of the motor cable on the motor terminal box using EMC cable glands
Shield bonding of the signal, bus, and encoder cables
Shield bonding of the encoder cable on the housing of the speed encoder
Signal, bus, and encoder cables in the converter must be routed as close as possible
to the cabinet frame or on grounded plates at a large distance from the power cables
