The length of the narrow part is based on 2.6 mm – the outer diameter of a single-core coaxial cable. Therefore, the narrow part does not always completely overlap the text area, and sometimes it is shorter than the text area. When such a label is affixed to the cable with a bigger diameter, the remaining narrow part is folded inside the label so that only the tidy text area is visible from outside.

3.  Fold up the Label

Fold up the label upward along the dotted line and stick it, as shown in Figure D-7 (3).

D.4.2  Affixing Labels to the Power Cable

Remove the label from the bottom page, and affix it to the identification plate on the cable tie. The label should be stuck to the rectangular flute, and should be stuck to any one side of the identification plate. Make sure to affix the labels on the same side of the identification plates. In principle, the cable ties are bundled 2 cm away from the connectors, or at other positions in special circumstances.

Cable ties should be bundled on both ends of a cable. After the bundling, the identification plate should face the right or upside. That is, it faces the right when the cable is laid vertically, while faces upside when the cable is laid horizontally. Make sure the label is facing out, as shown in Figure D-8.

D.5  Common Engineering Labels

D.5.1  Engineering Labels for Power Cables

1.  Scope of Application

The labels are affixed to both ends of the DC power cables that provide power for the cabinets. The DC power cables here include the power cable, PGND cable, and BGND cable.

The labels for DC power cables are affixed to one side of the identification plates on cable ties. Table D-2 shows the information carried on the labels for the DC power cables:

Table D-2 Information on labels affixed to the DC power cables

Content

Meaning

MN(BC)- –48V1

MN(BC): BC is written right under MN.

On the loaded cabinet side, only MN is used to identify the cabinet.

On the side of power distribution equipment, MN indicates the row and column numbers of the control cabinet and cable distribution box. BC indicates the row and column numbers of the –48 V wiring terminal of the power distribution equipment. If there is no row number or column number, or the wiring terminal can be identified without them, BC can be omitted. BGND and PGND have no row and column number for identification.

MN(BC)- –48V2

MN(BC)-BGND

MN(BC)-PGND

The label only carries location information about the opposite equipment, the control cabinet or the cable distribution box, while information of the local end is not necessary. Table D-2 lists the information for two –48 V power supplies on the label. The information for other DC voltages (such as 24 V, 60 V) should be given in similar methods. Make sure that labels are affixed in correct direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face outside, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure D-9.

Figure D-9 Example of the labels on the DC power cable

The label affixed to the cable at the loaded cabinet side bears “A01/B08– -48V2”. It indicates a –48V2 power cable, which comes from the eighth wiring terminal on the second –48 V busbar in the power distribution cabinet located at Row A and Column 01 in the equipment room.

The label affixed to the cable at the side of power distribution cabinet bears “B03– –48V2”. It indicates a –48V2 power cable, which comes from the loaded cabinet at Row B and Column 03 in the equipment room.
