Consider such an alternative at an early stage in the design to ensure that it is located in the
cabinet to give optimum cable lengths.
Wiring is routed to different transducers and loads in the installation from the marshalling.
It is important that the leads to and from a transducer for an electric signal be in the same cable.
This requirement means that it is logical to distribute the voltage supply and the neutral from the
controller or marshalling. The costs of cable and cable installation work can often be reduced by
routing a multi-core cable to coupling boxes mounted nearby, from which cables can be
connected to individual objects. More detailed voltage distribution and object fusing is possible
in a coupling box than in a connection unit. The fusing used in the connection unit can then be
dimensioned to protect the cable in the event of a short circuit.
