Additional US requirements

Type MC continuous corrugated aluminium armor cable with symmetrical grounds or
shielded power cable must be used for the motor cables if metallic conduit is not
used. For the North American market, 600 VAC cable is accepted for up to 500 VAC.
1000 VAC cable is required above 500 VAC (below 600 VAC). For drives rated over
100 amperes, the power cables must be rated for 75

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 resistor, and control
wiring. When conduit is employed, type MC continuous corrugated aluminium armor
cable or shielded cable is not required. A dedicated ground cable is always required.
Note: Do not run motor wiring from more than one drive in the same conduit.
