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

    Hello,

    I am confused why you would select red for your DC power circuits when EN 60204-1 states that these should be black, with red being for AC control?

    That is taken direct from the standard, not any guidance from another organisation.

    Which document are you referring to by the way please as there is no link in your post?
