How to Install the PDU
Attach the cord
retention trays
Attach the cord retention trays to the PDU, using four flat-head screws
(provided) per tray.
Attach cords to the tray
Attach a cord to the tray by looping the cord and securing it to the tray,
using a wire tie (provided).
Each cord must be secured to the tray so that you can
unplug it from the PDU without removing the wire tie.
Mounting options
Install the PDU in the rear of the NetShelter VX Enclosure, in the cable
channel directly behind the rear vertical mounting rails. You can install
the PDU in one of two ways: using toolless mounting pegs (provided) or
the mounting brackets (sold separately).
You can order a rack-mount bracket kit from APC

How to Install the PDU
Toolless mounting
1. Slide the mounting pegs into the holes located in the channel in the
rear panel of the enclosure.
2. Snap the PDU into place by pushing it downward until it locks into
You can mount two PDUs on one side of the enclosure by
using the toolless mounting method.

How to Install the PDU
You can order a rack-mount bracket kit from APC (AR8116BLK). The
brackets attach to the PDU in either of two directions, shown in the
figures in step 1. Consider the orientation of the PDU in the enclosure
before attaching the brackets. A recessed orientation allows the PDU to
be mounted flush with the enclosure; a raised orientation allows you to
route cables through the channel (see the figures in step 2).
1. Attach two brackets to the rear of the PDU, using two pan-head
screws (provided in the bracket kit) for each bracket.

– Raised orientation
You can mount two PDUs on one side of the enclosure by
using the raised orientation.

and bottom positions in the channel where the brackets align with
the holes. Tighten the screws to secure the PDU to the enclosure.
