Motor power connections should be pulled together in a metallic
conduit or be in a sheathed cable. Four conducts must be used (3
for motor power and one ground). Ground must be terminated in
the motor conduit box and in the drive. Conduit or sheath must be
grounded and continuity of ground maintained.
