Do power wires need to be installed in separate conduits for AC drives?

Issue:
Power and Control wire installation for all AC variable speed drives

Product Line:
All Altivar drives

Resolution:
Good wiring practice requires the separation of control wiring from power wiring. Power wiring to the motor must have the maximum possible separation from all other power wiring, whether from the same drive controller or other drive controllers. Do not run power and control wiring, or multiple power wiring, in the same conduit. This separation reduces the possibility of coupling electrical transients from power circuits into control circuits or from motor power wiring into other power circuits.

Use of shielded cables does not reduce nor eliminate the need for cable separation.

Refer to the installation manuals for the specific drives for additional information.
