Planning the electrical installation 65

Separate control cable ducts
Put 24 V and 230 V (120 V) control cables in separate ducts unless the 24 V cable is
insulated for 230 V (120 V) or insulated with an insulation sleeving for 230 V (120 V).

Continuous motor cable shield or enclosure for equipment on the
motor cable
To minimize the emission level when there are safety switches, contactors,
connection boxes or similar equipments on the motor cable between the drive and the
motor:
• European Union: Install the equipment in a metal enclosure with 360 degree
grounding for the shields of both the incoming and outgoing cable, or connect the
shields of the cables otherwise together.
• US: Install the equipment in a metal enclosure in a way that the conduit or motor
cable shielding runs consistently without breaks from the drive to the motor.
