I said we don't use brown. I didn't say it can not be used.
Standard colours?
IEC 60204-1 parag: 13.2.4:
"When colour-coding is used for identification of conductors (other than the protective conductor (see 13.2.2) and the neutral conductor (see 13.2.3), the following colours may be used:
BLACK, BROWN, RED, ORANGE, YELLOW,GREEN,BLUE (including Light Blue), VIOLET, GREY, WHITE, PINK, TURQUOISE.
For safety reasons, the colour GREEN and colour YELLOW should not be used... (see my previous post)"
There are no standards but recomendations like:
IEC 60204-1 parag: 13.2.4:
"BLACK: AC and DC power circuits
RED: AC control circuits
BLUE: dc control circuits
ORANGE: excepted circuits in accordance with 5.3.5"
Yeah, I was afraid we would have to use these IEC standard, altought it makes no sense to me, using the same colour dor DC+ and DC-
We don't use it in our machines, we have our colours (pretty much the same as the above posts), but for some machines the costumer safety people demands that we follow the standards ( and can you believe they are not so rigid on the actual safety aspects of the machine...)
