— a step ladder to access the top of the 212.5 cm (7-ft.) NEBS 2000
frame
— a screwdriver with a very large slotted bit to fasten the screws of the
side panel
— a light hammer to tap plastic caps onto the panel screws
• Fastening the ground cable assembly (NTRU0102) from kit NTRU0128
provides additional grounding because the side panel brackets are
fastened to painted surfaces. The cable is 30.5 cm (1 ft) long and size
10 AWG (5.26 mm
2
).
Procedure steps
1 Assemble the side 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)
• “Upper brackets for frame panels” (page 527)
• “Lower brackets for frame panels” (page 528)
2 See the figures “Side panels, exploded view” (page 529) and “Installed
front, rear, and side panels” (page 531)“. Observe the position of the
upper and lower pairs of brackets. Align a bracket according to the figure.
3 When the extended cable management brackets are installed or to be
installed on the same side of the frame as the panel to be installed, fasten
the spacer bracket (P0902817) from kit NTRU0365 to the frame using the
3 provided thread-forming 6-mm (15/64-in.) hex-head screws. Tighten the
screws to snug plus a 1/4 turn. See the figure “Lower brackets for frame
panels” (page 528).
4 Repeat step 3 for the other 3 spacer brackets, moving sideways. After the
second bracket, temporarily position the panel beside the pair of brackets
to verify if the mounting holes align. If not, reposition the brackets until
they align.
5 From NTRU0128, fasten the 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. See the figures “Upper
brackets for frame panels” (page 527)“and “Lower brackets for frame
panels” (page 528). The upper brackets are oriented the same way as the
lower.
