Location and Mounting
- Choose a mounting location that is not exposed to condensing humidity, or temperatures beyond the limits of +20 to +130F (-7 to +55 C). If installing outdoors, a sun shield may be necessary to protect against the elevated temperatures that can be produced on exposed objects during a hot day.
- This location should ideally be within 5 feet of a standard RJ- 11 phone jack and a grounded 120 VAC power outlet (or other power source as applicable). Allow at least 3 inches clearance below the lower edge of the enclosure, to allow access to the connection ports that are located there.
- Mount the RTU on centers of 6" x 11-3/8", using the external mounting ears on the enclosure. #10 or 3/16" bolt sizes are best.
- Alternatively, the RTU may be mounted in a standard 10" x 12" x 6" NEMA 12, 4 or 4X enclosure. The RTU alternative internal mounting centers of 8-1/4" x 10-1/4" will match the threaded mounting inserts on most such enclosures.
