INSTALLATION
This installation should be made by qualified service personnel
and should conform to all local codes. Safeguards must be
taken to avoid unintentional operation by employees and
maintenance personnel working about the premises, by falling
objects, by customers, by building vibration, and by similar
causes.
Preparation
There are many user settable switches. If the unit is not set up
correctly, damage to this unit and any other devices connected
to it may result. Check all wiring and cabling before applying
power.
Mounting
Receivers are surface mounted and when used indoors can be
mounted with any orientation. Units to be mounted outdoors
must be securely mounted to a suitable surface, with the
hinged side facing to the left. The box should be mounted near
the camera(s) to be controlled to minimize voltage drop in the
wiring.
The housing is a standard NEMA 4, fiberglass reinforced
polyester, non-corrosive enclosure. The housing size is 17.5"
H x 14.8" W x 6.7" D.
Mount the unit with four 1/4" bolts appropriate to the type of
mounting surface. See Figure 2 below for mounting
dimensions.
For mounting to wood studs, use lag bolts (with a drilled pilot
hole) or wood screws which will penetrate the wood for at
least 2-1/2 inches. In concrete use lead or plastic anchors, or
expansion bolts, with at least a 70 pound pullout rating,
installed according to the manufacturer's instructions. For
mounting to steel surfaces, drill four bolt clearance holes and
use bolts with lockwashers and nuts. When mounting to
drywall (gypsum) wallboard, material must be at least 1/2"
thick, and the unit must be mounted with toggle bolts.
