Conduit
Where conduits must be coupled together, bridge the joint with a ground conductor bonded
to the conduit on each side of the joint. Bond the conduits also to the drive enclosure. Use
separate conduits for input power, motor, brake resistors, and control wiring. Do not run
motor wiring from more than one drive in the same conduit.
Armored cable / shielded power cable
The motor cables can be run in the same cable tray as other 460 V power wiring. Control and
signal cables must not be run in the same tray as power cables. Six conductor (3 phases and 3
ground) type MC continuous corrugated aluminum armor cable with symmetrical grounds is
available from the following suppliers (tradenames in parenthesis):
• Anixter Wire & Cable (Philsheath) • BICC General Corp (Philsheath)
• Rockbestos Co. (Gardex) • Oaknite (CLX).
Shielded power cables are available from Belden, LAPPKABEL (OLEFLEX) and Pirelli.
