EMC INTERFERENCE

Use shielded cables for motor and control wiring, and separate cables for input power, motor wiring, and control wiring. Failure
to isolate power, motor, and control cables can result in unintended behavior or reduced performance. Minimum 200 mm (7.9 in)
clearance is required between power, motor, and control cables.
