Table A-9 Information on labels affixed to the DC power cables
Content Meaning
MN(BC)--48V1
MN(BC)--48V2
MN(BC)-BGND
MN(BC)-PGND
MN(BC): BC is written right under MN.
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 the control
cabinet and distribution box, BC identifies the row and
column number of the -48V connecter (if there is no row
number or column number, or the connecter can be identified
without them, BC can be omitted). BGND and PGND have no
row and column number for identification.
The label only carries location information about the opposite equipment, the control
cabinet or the distribution box, while information of the local end is not necessary. Table
