B Engineering Labels for Cables
The labels for DC power cables are affixed to one side of the identification plates on cable ties.
For details of the labels, see

The label only carries location information about the destination direction of the power cable
while information of the local end is not necessary. That is, the label only carries location
information about the opposite equipment, the control cabinet, or the distribution box. Table
D-8 lists the information on two -48 V power supplies on the label. The information on other
DC voltages, such as 24 V and 60 V should be given in similar methods.
Make sure that labels are affixed in the correction direction. That is, after the cable ties are
bundled onto the cable, the identification plates with the labels should face up, and the text on
the labels in the same cabinet should be in the same direction. For details, see

The meaning of the label in
l
B-20
Meaning
MN(BC): BC is written right under MN.
B: chassis number, numbered in the bottom-top order with two digits,
for example, 01.
N: power socket number , numbered as 1 to 3 in the bottom-top and left-
right orders.
On the loaded cabinet side, only MN is used to identify the cabinet.
On the power cabinet side, MN identifies the row and column number
of the power distribution equipment like a control cabinet and
distribution box, and BC identifies the row and column number of the
-48 V connector. If there is no row number or column number, or the
connector can be identified without them, BC can be omitted. It is
unnecessary for BGND and PGND to identify the row and column
number.
On the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates that the cable
is -48 V DC supply, which is from the eighth connector on row B of -48 V bus bar in the
cabinet on row A, and column 1 in the equipment room.
