5.4.1.6 Contents of Engineering Labels
Contents of Labels for Power Cables
Labels for power cables are affixed on only one side of the identification plates. On the labels,
there is information (the part after the word "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.
Contents of Labels 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.
shows the information on both
sides of the labels affixed to the signal cables.
l
Area 1 contains the location information of the local end of the cable.
l
Area 2 (with the word "TO:") contains the location information of the opposite end of the
cable.
l
Area 3 has been folded up inside the label.

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.
In other words, the information in Area 1 at one end is the same as the information in Area 2
at the other end of the cable.
5.4.1.7 Precautions for Using Engineering Labels
When using labels, pay attention to the following points:
l
When printing, writing, or attaching labels, keep the labels clean.
l
Since the label paper is made of moistureproof material, ink-jet printers and ink pens
cannot be used to print and write labels.
l
Labels should be attached neatly. New-type labels are L-shaped. If they are pasted at
incorrect locations or in the incorrect direction, the appearance of the device is affected.
l
Power cable ties should be attached in the same positions on power cables, with
identification plates on the same side.
l
The positions of "up", "down", "left" or "right" are all based on the viewpoint of the
engineering person who is working on the label.
