Engineering labels for AC power cords
These labels are affixed to the AC cables 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 about the local end is not necessary. Make sure labels are affixed in the correct direction.
After the cable ties are bundled onto the cable, the identification plates with the labels must face up, and
the text on the labels in the same cabinet must be in the same direction, as shown in
