If the spacer brackets from NTRU0365 are not required, fasten the panel
brackets from NTRU0128 directly to the upper and lower frame in the
holes provided.
With or without the spacer brackets, ensure all 4 panel brackets extend
away from the frame on an even vertical plane.
6 From NTRU0128, using 2 of the provided 10-mm (3/8-in.) hex-head
screws and lock washers, fasten the grounding cable assembly
(NTRU0102) from the frame upright to an upper bracket. Position a
toothed lock washer between each end-cable eye loop and the upright or
the bracket. Use the third hole from the top of the upright at one end of the
cable, and a lower middle hole on the side of the upper bracket nearest
the upright. For the position of the cable, refer to the figure “Side panel
grounding cable” (page 530).
7 Position the side panel against the 4 brackets with the smooth side facing
outwards as shown in the figure “Side panels, exploded view” (page 529).
Have a helper hold the panel off the floor until 2 top screws are fastened.
8 Align the 4 upper holes in the side panel with the 4 holes in the upper
brackets.
9 While holding the panel aligned in position (off the floor), loosely fasten a
screw (A0377259) and special washer (A0377315) through a corner hole.
Loosely fasten another screw and washer through the opposite end hole
so that the panel is evenly supported.
10 Align and loosely fasten a screw and washer through the remaining 6
panel holes, starting at a bottom corner.
11 Tighten all screws to snug plus a 1/4 turn.
12 Lightly tap a plastic cap onto each special washer.
