• Fastening the ground cable assembly NTRU0102 from kit NTPX4050
provides additional grounding because the side panel brackets are
fastened to painted surfaces. The cable has eye-loop connectors at each
end and is 30.5 cm (1 ft) long and size 10 AWG (5.26 mm
2
).
Procedure steps
1 Assemble the side panel brackets. A side bracket pointing frontwards
(facing the side of the frame) and a side bracket pointing rearwards have
the same part number. Refer to the figures
• “Assembly of a side panel bracket NTRU0371, left and right, upper or
lower” (page 526)
• “Extended side panels, exploded view” (page 521)
2 In the figure “Extended side panels, exploded view” (page 521)“, observe
the position of the upper and lower pairs of brackets.
3 Fasten the side panel brackets onto the spacer brackets using the 4
provided thread-forming counter-sunk 6-mm (15/64-in.) screws. Tighten
the screws to snug plus a 1/4 turn. The upper brackets are oriented the
same way as the lower.
Ensure all 4 panel brackets extend away from the middle of the frame on
an even vertical plane.
4 Using 2 of the provided 10-mm (3/8-in.) hex-head screws P0601478 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.
5 Position the side panel against the 4 brackets with the smooth side facing
outwards as shown in the figure “Extended side panels, exploded view”
(page 521).
6 Have a helper hold the panel off the floor to align the 4 upper holes in the
side panel with the 4 holes in the upper brackets.
7 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 corner
hole so that the panel is evenly supported.
