The proximity of these two sets of wires will in most cases cause problems of induced disturbance or over time malfunctions or damage to the components The ideal solution is to house these two circuits in two separate cabinets Sometimes this is not possible and therefore the power part and the control part must be installed in two separate areas inside the same panel For the control signals it is recommended to use shielded cables with twisted wires If the control cables have to cross over the power cables the intersections must be as near as possible to 90 degrees always avoiding running the control cables parallel to the power cables Carel highlights the following warnings Use cable ends suitable for the corresponding terminals Loosen each screw and insert the cable ends then tighten the screws When the operation is completed slightly tug the cables to check they are sufficiently tight separate as much as possible the sensor signal digital input and serial line cables from the cables carrying inductive loads and power cables to avoid possible electromagnetic disturbance Never insert power cables including the electrical cables and probe signal cables in the same conduits Do not install the sensor cables in the immediate vicinity of power devices contactors circuit breakers or similar reduce the path of the sensor cables as much as possible and avoid spiral paths that enclose power devices e avoid touching
