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

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

It is normal for the +/- 24VDC wiring to be the same colour.

Is this power, or control?

As has been suggested, alpha numeric ID's are required on the wiring anyway.

As mapj1 says, you can use alternative colours, but I always recommend that clients stick to the standard and claim your presumption of conformity given by following the EN's.
