Power Cable Specifications

A variety of cable types are acceptable for drive installations. For an in-depth discussion of cable types, including a table of maximum motor cable lengths, see the Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives, publication DRIVES-IN001.

Power Cable Types Acceptable for 400…690 Volt Installations

ATTENTION:
Risk of injury or equipment damage exists.
National codes and standards (NEC, BSI, and so forth) and local codes outline provisions for safely installing electrical equipment. Installation must comply with specifications regarding wire types, conductor sizes, branch circuit protection, and disconnect devices. Failure to do so can result in personal injury and/or equipment damage.

  • Signal wires should be separated from power wires by at least 0.3 meters (1 foot).
  • The use of shielded wire for AC input power may not be necessary but is always recommended.
  • The minimum insulation rating for input power wire must be at least equal to the nominal system voltage rating.
