Additional US requirements


Type MC continuous corrugated aluminum 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 V AC cable is accepted for up to 500 V AC.
1000 V AC cable is required above 500 V AC (below 600 V AC). For drives rated over
100 A, the power cables must be rated for 75

Conduit

Separate parts of a conduit must be coupled together, bridge the joints with a
ground conductor bonded to the conduit on each side of the joint. Bond the
conduits also to the drive enclosure and motor frame. Use separate conduits for
input power, motor, brake resistor, and control wiring. When conduit is employed,
type MC continuous corrugated aluminum armor cable or shielded cable is not
required. A dedicated ground cable is always required.
WARNING! Do not run motor wiring from more than one drive in the same
conduit.
