Planning the electrical installation 75
 Separate control cable ducts
Lead 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 safety switches, contactors, connection boxes
or similar equipment are installed 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.
Implementing thermal overload and short-circuit protection
 Protecting the drive and input power cable in short-circuits
Protect the drive and input cable with fuses as follows:
24 V 24 V
230 V
(120 V)
230 V
(120 V)
