Appendix A Engineering Labels for Cables
A-8
A.1.6 Information Carried on Labels
I. For power cables
Labels for power cables are only affixed on one side of the identification plates. On the
labels, there is information (the part after the mark “TO:”) about the location of the
device on the other end of the cable, like the location of control cabinet, distribution box
or power socket.
II. For signal cables
The two sides of the label affixed on the signal cable carry information about the
location of the ports connected to both ends of the cable, as shown in Figure A-9.
The information is given like this:
z Area 1 contains the location information of local end of the cable.
z Area 2 (with the mark "TO:") contains the location information of the opposite end
of the cable.
z Area 3 has been folded up inside the label.
Area 3 Area 1

Figure A-9 Printed parts on the label for signal cables
Seen from the cabling end of the equipment, the text part of the label is on the right side
of the cable. The side with “TO:” that is facing outside carries the location information of
the opposite end; and the other side carries the location information of the local end.
Therefore, the information in Area 1 at one end is the same as the information in Area 2
at the other end of the cable, and vice versa. In other words, the local information at one
end is called the opposite information at the other end.
A.1.7 Remarks
z When printing/writing and affixing labels, pay attention to keep the labels clean.
z Since the label paper is made of moistureproof and waterproof material, ink-jet
printers and ink pens are forbidden for printing and writing labels.
z Labels should be affixed with good order in alignment.
z Cable ties should be bundled in the same position of power cables, with
identification plates on the same side.
z The positions of “up”, “down”, “right” or “left” are all based on the viewpoint of the
engineering person who is working on the label.
