Its amazing how much head scratching there is to be done, when trying to arrange machine electronic components into a bespoke control cabinet. The aim is to keep the 240V AC and 12V DC power away from the low volt signal control wires.

So I have come up with this arrangement, and need to know if there could be complications in any way, especially heat?

Cheers
