11.5 Unpack the MPC, remove protective
material, and mount the MPC on the
adapter. Tighten thumbscrews to secure the
MPC on the adapter.
11.6 Loosen the locking thumbscrews, swing
the MPC full left, and lock in position.
11.7 Remove the plastic cover from the
protector terminal field by removing the
retaining screw.
11.8 Unlock the adapter, switch the MPC
full right, and lock in position.
11.9 Push the four 25-pair groups through
the four slots in the MPC mounting bracket;
the group with pair-count 1-25 must be in
the top slot followed by pair-counts 26-50,
51-75, and 76-100 in the other slots in
descending order. Remove any slack by
reaching around the MPC and pulling and
pushing the wires into the protector terminal
field.
11.10 At the rear of the connector,
bring groups 1-25 and 26-50 together, and
secure them to the cable mounting stud on
the MPC mounting bracket using a cable tie.
Repeat for groups 51-75 and 76-100.
11.11 Lace the two 50-pair groups
from the rear tie wraps on the MPC to the
first transverse arm below the MPC.
11.12 Unlock the adapter, swing the
MPC full left, and lock in position.

Using standard wire-wrap
tools, procedures and the wiring diagram in
Figure 10, terminate the cable pairs on the
long-pin terminals of the protector terminal
field.
11.14 Dress all wires on protector
field, and replace the cover over protector
terminals.
11.15 Unlock the adapter, swing the
MPC to center position.
11.16 Loosen, but do not remove,
the screws securing the adapter to the frame
vertical and the thumbscrews securing the
MPC to the adapter.
11.17 Lift adapter and MPC off the
frame vertical, and remove the adapter from
the MPC mounting bracket.
11 .18 Hang the MPC by its mounting
bracket slots on the two screws in the frame
vertical. Tighten the screws.
NOTE:
Mount the first MPC on the appropriate
frame verticals (Figure 9):
• Compact (PDF) 356 mm (14 in.) from floor or
203 mm (8 in.) from ladder guard rail.
• Conventional (PDF) 305 mm (12 in.) from
floor (Figure 6).
NOTE:
Position the MPC so that the plastic stud
on the top of the connector immediately below
engages the slot on the bottom of the connector being
mounted.
11.19 Dress the binders down the frame, and
tie to the transverse arms as required.
