Appendix A Engineering Labels for Cables
A-15
Note:
z In the power distribution box (or the first power cabinet of a row in the transmission
machine room), every terminal block on the -48V connector bar has a numeric
identification. For example, in the above label of “A01/B08--48V2”, “08” (or
sometimes “8”) is the numeric identification of the terminal block.
z PGND and BGND are two copper bars, on which the terminal blocks are
short-circuited, therefore which terminal is connected makes no difference. It is only
necessary to give the row and column of the power distribution box, instead of giving
the specific serial number of the terminal block on the copper bar. For example, if
the label on the loaded cabinet side is “A01-BGND”, it means that the power cable is
a BGND that connects BGND copper bar in the power distribution box on Row A,
Column 01 in the machine room. Information on the labels for PGND cables should
be given in the similar way.
A.4.2 Labels for AC Power Cables
The labels are affixed to the AC cables that provide power for the cabinets, and the
protection grounding cables, including the POWER, PGND, and BGND cables. The
220V AC cables and related PGND and BGND cables are covered with insulating
sheath, so the labels only need to contain the words of “AC" and the cabinet number.
The labels for AC power cables are affixed to one side of the identification plates on
cable ties.
I. Meaning of the label
Table A-6shows the information carried on the labels for the AC power cables.

Content Meaning
MN-AC
MN: serial number of the cabinet or the socket where the power is led in
The location of the socket is marked out according to onsite situation. If
the sockets can be identified by row number and column number, they
can be numbered following the same rule for the cabinets. If the
sockets cannot be identified by rows and columns, specify the detailed
locations to avoid confusing with other sockets.
The label only carries location information about the opposite equipment and the power
socket, while information of the local end is not necessary.
