I have another issue that just came up. Can anyone supply the exact color code presented in IEC 584. This is for a similar panel that is going to Egypt. There are some 4-20ma two wire signals and some 24VDC two wire lines to solenoids. We used red for positive and black for negative. This is allready done and now their engineers have come back asking for white for positive and black for negative. Does IEC 584 require this?
