Appendix B –CE Compliance
B-3
Motor Cable
D The cable between the controller and motor
must be a 4-wire shielded cable (three phases
and ground). Refer to Figure B.2 and
Figure B.3.
D Do not exceed the maximum motor cable
length for the specific line filter module used.
D Inside the shielded enclosure, shielded motor
cable must be used as close to the controller’s
output terminals as possible. The shield must
be solidly connected to the PE terminal of the
controller.
D Where the shielded motor cable exits the
enclosure, an EMC-tested cable clamp, or
metal conduit must be used to solidly connect
the cable shield to the enclosure.
D The shield on the motor side must be solidly
connected to the motor housing with an
EMC-tested cable clamp, or conduit,
providing good conductivity from the cable
shield to the motor housing.
