68 Guidelines for planning the electrical installation
A diagram of the cable routing is shown below.
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 in 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.
