It is an absolute requirement that the wires/terminals of the intrinsically safe circuits
cannot
get
into contact with the wires of the other cables. The distance between cables/wires therefore must
be at least 50 mm.
It is recommended to fasten the cables/wires in a way that they, even in case of an error,
cannot
get into contact with each other. Make the wire ends as short as possible.
