2.2.1.1. Wall Mount Power Supply
Figure 10 shows the power supply mechanical drawing and key holes to be used when mounting it on the wall. Note:
As shown in Figure 11, when mounted on the wall –unit shall be installed within “3 feet” from the ground, and
†
within 20 feet from the STAR Receiver
The keyholes are designed for either
†
#6 Drywall (bugle head) or #6 wood screws if the unit is being fastened to a wooden surface.
–
For a solid wood mount, box nails can be used, providing the head diameter is more than .28” and less than .30”
–
in diameter and the shank of the nail is at least 2” long.
If the unit is being fastened to a metal surface that is at least .1875” thick, 6-32 pan head machine screws may
–
be used.
If the unit is being fastened to drywall/plaster, 1/8 Molly or Toggle bolts must be used.
–
The recommended mounting procedure is:
1. To use drywall mounts (“Molly Bolts” are preferred) for that purpose (these, or toggle bolts, offer a pull-down
force more than 4X the industry-standard, and are highly recommended in areas prone to seismic activity).
2. Bugle-head #6 Drywall screws (coarse thread) are acceptable, if all 3 tie down points are used, offering an
industry-standard of a pull-down strength of at least 4X the weight of the unit.
3. If the walls are of at least 1/2” wood (plywood, for example), nails can be used.
In addition, the cable must be properly dressed and supported. The cables, both AC and DC, are to drop down from the
power supply with a drip or service loop. They are to be supported at least once within 18” of the unit, and according
to best industry practice (and NEC) at intervals of no more than 36”. Cables can be run in conduit, providing (a) the
conduit is not hanging on the cables, (b) the service loop exists, and (c) there is at least one support/tie-down on the
cables between conduit and power supply.
