3-5.1 Installation Instructions
The enclosure comes supplied with two hanging brackets mounted at the top and bottom of the backside of the
enclosure. The wall mounting plate also comes attached to the enclosure by means of one 1/4-20 screw. The following
procedures must be used to attach the enclosure to the wall.
Note that the enclosure can be attached to the wall either before or after mounting the WAVEXpress inside the
enclosure.
Step 1
Open the enclosure door, and move the swing frame to expose the single 1/4-20 bolt which is used to
attach the mounting plate to the back wall of the enclosure for shipping purposes.
Step 2
Unscrew the 1/4-20 bolt to free the wall mounting plate from the enclosure. Refer to Figure 3-13 : "Out-
door enclosure wall mount" on page 50 for an indication of the position of this bolt.
Step 3
Mount the wall plate to a suitable wall, as detailed in the following note. The plate should be mounted so
that the tabs on the top and bottom of the plate face outwards, away from the wall. A sketch detailing
hole placement is shown in Figure 3-14 : "Hole placement for the wall mount plate" on page 51.
No mounting hardware is supplied with the plate as the type of hardware used is determined by the
material of the wall to which the enclosure is mounted. However, the six mounting holes of the wall plate
can accommodate up to 5/16” diameter hardware.
Step 4
Hang the enclosure form the top and bottom of the mounting plate's lip. This is accomplished by raising
the enclosure slightly higher than the mounting plate and sliding it in position over the two plate's lips.
The brackets supplied for mounting the interWAVE enclosure are made of
stainless steel. Each bracket is rated at 450 pounds, normal load when mounted
to the enclosure and to a suitably strong wall with 8mm (5/16”) diameter
stainless steel machine screws and nuts, or other fasteners suitable for the wall
material, such as lag screws for wood, or lag screws in concrete anchor sleeves for
solid concrete or masonry walls. For more information on a suitable mounting
wall, refer to Chapter 2.
The mounting location should be selected so that it is capable of supporting
160lbs from four 8mm (5/16”) screws. Examples of typical materials include:
• Poured concrete aggregate walls, 6" or greater in thickness. Holes may be
drilled of a diameter and depth sufficient to accept the lead concrete expan-
sion. Anchors typically are used with hex-head coarse thread lag screws. The
lag screws should penetrate the wall by at least 2", requiring a sleeve hole of at
least 2.5" deep.
• Wood timber framed wall with upright members 4" square cross-section or
greater, with spacing equal to the mounting dimensions of the box. Lag screws
should penetrate the wood by at least 3", and be screwed into pilot holes of
diameter 1/32” greater than the minor diameter of the thread. Soap may be
applied to the screw threads to ease the screwing operation.
