C.5 Engineering Labels for Power Cables
C.5.1 Labels for DC Power Cables
The labels apply to the DC cables that provide power for the cabinets, and the
protection grounding cables, including the -48V, PGND, and BGND cables. The labels
for DC power cables are on one side of the ID plates on cable ties.
I. Meaning of the Label
Table C-6 shows the information carried on the labels for the DC power cables:
Table C-6 Information on labels affixed to the DC power cables
Content
MN(BC)--48V1
MN(BC)--48V2
MN(BC)-BGND
MN(BC)-PGND
The label only carries location information about the opposite equipment, the control
cabinet or the distribution box. The information of the local end is not necessary. Table
MN (BC): BC is right under MN.
On the load cabinet side, MN alone can identify the cabinet.
On the power cabinet side, MN identifies the row and
column number of the power distribution equipment such as
the control cabinet and distribution box. BC identifies the row
and column number of the -48V connector (if there is no row
number or column number, or the connector can be
identified without them, BC can be omitted). BGND and
PGND have no row and column number for identification.
