Frequently Used Engineering Labels
This section describes the frequently used engineering labels. The other labels are
omitted here. You can perform the operation as required on site.
?.1. Engineering Labels for Power Cables
The labels are attached to the DC cables that provide power for the cabinets, and
the protection ground cables, including the -48 V, PGND, and BGND cables. The
labels for DC power cables are attached to one side of the identification plates on
cable ties.

label. The information for other DC voltages (such as 24 V, 60 V) should be given
in similar methods. Make sure that labels are attached in correct 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

Meaning
MN (BC): BC is written right under
MN. On the loaded 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 -48 V
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. On the power cabinet
side, only MN is used to identify the
cabinet.
