NOTE
Cabinet joining brackets are provided in the field kit for securing each cabinet at
the top and bottom. A small flat bracket joins the top of the cabinets and a larger angle
bracket joins the cabinets at the bottom. The small flat bracket is attached to the cabinet
tops first.
26.
Locate a small flat bracket, four washers, and M4 screw from the field kit. Align
the holes in the small flat bracket over the hole in the top of UPM 1 and the door
hinge screw hole on the IAC. Use the four washers between the bracket and the
top of the UPM to match the thickness of hinge on the IAC. Secure the bracket to
the UPM using the M4 screw, and to the hinge on the IAC using the screw
removed in Step 25 (see Figure 3-11).
27.
Locate a large angle bracket, M4 screws, and large nut from the field kit. Place one
end of the bracket over the bolt on the bottom side of the lower hinge on the
IAC, and loosely secure the bracket to the hinge with the large nut (see
Figure 3-11).
28.
Align the holes in the other end of the bracket with the holes in the bottom
right-hand side of UPM 1 (see Figure 3-11). Secure the bracket with M4 screws
from the field kit.
