E.4. Zero-U Pocket Bracket Mounting (MPC-20V Series Only)The Zero-U Pocket Brackets allow you to mount MPC-20V series units in APC© style
racks, that include a pocket or channel for zero unit mounting as shown in Figures E.6
and E.7.
The Zero-U Pocket Brackets allow MPC-20V series units to be mounted directly into the
channel or pocket at the rear of the rack, and can either be nested inside the pocket
in order to use as little space as possible, or mounted on top of the pocket, in order to
provide a convenient cavity for cable routing. When the Zero-U Pocket Bracket is used,
the MPC-20V will always be mounted facing the interior of the rack.
1. Attaching the Zero-U Pocket Brackets to the MPC:
a) Determine whether the MPC-20V will be nested within the rack pocket, or will
be mounted outside the pocket in order to provide a cavity for cable routing.
b) Insert the screws supplied with the bracket into the three holes in the center
of the Zero-U Pocket Bracket and then thread them into holes 4, 2 and 5 (see
Figure E.1) on the back of the MPC-20V unit as shown in Figures E.6 and E.7.
2. Attaching the Zero-U Pocket Brackets to the Equipment Rack: Align the MPC
with the rack pocket and then use appropriate retaining screws to secure the
Zero-U Pocket Brackets to the rack pocket as shown in Figures E.6 and E.7.
