cabinet side is "A01-BGND", it means that the power cable is a BGND that connects BGND
copper bar in the power distribution box in row A, column 01 in the machine room.
Information on the labels for PGND cables should be given in a similar way.
Engineering Labels for AC Power Cables
These labels are affixed to both ends of an AC power cable that provides AC power supply to
cabinets, including 110/220 V, PGND, and BGND cables. The 110/220 V AC cables and
related PGND and BGND cables are covered with an insulating sheath, so the labels need to
contain only the word "AC" and the cabinet numbers.
The labels for AC power cables are affixed to one side of the identification plates on cable
ties. For details, see
Table 13-44 Label content
Content
MN-(B)-ACn
The label only carries location information about the opposite equipment and the power
socket; information about the local end is unnecessary.
Make sure that labels are affixed in the 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 the same direction, as shown in

Meaning
MN: serial number of the cabinet or the socket where the power is led
in
B: chassis number, numbered in bottom-up order with two digits, for
example, 01.
n: power port number, numbered as 1 to 3 in bottom-up and left-to-right
order.
Serial number of the socket where the power is led in: the location of
the socket is marked according to the actual situation. If the sockets can
be identified by row numbers and column numbers, 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 confusion with other sockets.
