that connects RTN copper bar in the power distribution box on Row A, Column 01 in the equipment room.
Information on the labels for PGND cables should be given in the similar way.
Engineering labels for AC power cords
These labels are affixed to the AC cords that provide power for cabinets and protection grounding cables,
including POWER, RTN, and PGND cables. The 220 VAC cables and related PGND and RTN cables
are covered with insulating sheath, so the labels only need to contain "AC" and the cabinet number. The
labels for AC power cords are affixed to one side of the identification plates on cable ties.

Content Meaning
MN-AC
MN: Rack number (row number and column number in the equipment room) or the location
of the socket where the power is led in.
The location of the socket is marked according to onsite situation. If the sockets can be
identified by row number and column number, they can be numbered following the same
rule for the rack number. Otherwise, specify the detailed locations to avoid confusing with
other sockets.
The label only carries location information about the peer equipment and the power socket, while
information of the local end is not necessary. Make sure 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 must be in the same direction, as shown in
:
