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 All


    Many thanks for all your posts this has helped a lot.


    As the +/-24V DC is for power circuits I will use the colour red for both + & - voltage as stated in "Revised July 2006 to incorporate colour code and sizing recommendations in EN60204-1"


    But I will use cable identifiers to enable distinction
