EN60204-1:2006; +24VDC and -24VDC Wire Colours

FusionControlEng
Hello All


I have a piece of equipment that I am trying to wire up in accordance to EN60204-1:2006.


On the equipment I have AC mains (230VAC) coming in, this is then converted to +/-24VDC


According to the attached document, for AC and DC power circuits the wire colour black is used, so does this mean for my +/-24VDC, I use black for both the positive and negative?


This is strange as you would not be able to tell the difference between +24VDC and -24VDC


Could someone please clarify


Many thanks in advance

    I agree it seems odd, and therefore the standard does allow you to use other colours from the approved list if confusion may result.

    you could do worse than look at this ancient post.


    We also tend to use the coloured numbered sleeves examples, other sizes available  when we have to wire up mono-colour, but for us it tends to be a Def Stan Pink.
