Earthing?

[Edward]

Well yes, but these electronic elements need to be kept in some sort of box or small cabinet to protect them from swarf and keep it all tidy. I will do it and then let's see how it goes, I will report back to you guys with pictures. I think I am going to make my own box to size as I have plenty of 20 x 20 alu extrusion and with that and a few panels it can easily be made to measure.

However, I am tempted to run the cables all in one length, direct connection so to speak, with as few connectors as possible, just using glands for the entry points on the panel.
