Pre–mounting of Modular Cabinets in a Multi Cabinet System
When a system consists of two to four Modular Cabinets, the Modular Cabinets have to be
interconnected using an interconnection set for the Modular Cabinet. In this paragraph only the
shielding gasket of the interconnection set is discussed. The use of the other items of the
interconnection set is described in Paragraph 4.11. Refer to paragraph 4.4.
1.Remove the cover of the cabinet (see Figure 4–4):
-
Loosen the screws that secure the cover (1).
-
Lift the front cover approximately 3/8" (2).
-
Remove the cover by lifting the lower edge towards you (3).
2.
Remove the drawer for easy installation:
-
Open the drawer by pulling it towards you (4).
-
Release the drawer by pulling the lower side of the Modular Cabinet as indicated in Figure
4–4 (5) and remove the drawer (6). Replace the two front cover screws so that they do
not get lost.
3.
Remove the screw of the securing bar at the front of the Modular Cabinet and remove the
securing bar. Replace the screw so it does not get lost.
4.
Remove the conductive tape or break–out plates in the side panels that are going to be
positioned next to the other cabinet’s side panels.
5.
Place the shielding gaskets as indicated in Figure 4–5.
6.
Using the appropriate hardware (typically #8 wood or sheet metal screws), secure the
mounting bracket to the wall, so that the bottom side of the Modular Cabinet is about 5.25 ft.
above the ground. See Fig. 4-1.
7.
Hang the cabinet onto the mounting bracket and mark the location of the two retaining holes
on the bottom of the cabinet.
8.
Remove the cabinet and drill the lower mounting holes as needed.
9.
Repeat this procedure for the other cabinets. The cabinets must be placed against each other,
so that the shielding gasket will always have good contact with each other. For Modular
Cabinets with revisions R2 and R3 the distance adjustment plate can be used (see Figure 4–
6). (The space between the cabinets should never be more than .125".)
10. Continue with Paragraphs 4.7 or 4.8 as needed.
