General Information
Location Recommendations
The microprocessor module is mounted inside a molded
plastic enclosure for surface mounting. It is not
weatherproof making it applicable for indoor use only.
The Remote Human Interface Panel should be located in
an area to insure that the communication link between the
panel and the Unit or Units does not exceed 5,000 feet
maximum or pass between buildings, see
Table 1, p. 5 .
The low voltage AC power wiring to the Remote Human
Interface must not exceed three (3) ohms/conductor for
the length of the run, see
Table 2, p. 7 .
Ambient Temperatures and Humidity Limits are as
follows:
• Ambient Operating Temperatures
– 32 to 120 Degrees F
• 10 to 90% relative humidity, non-condensing
• Ambient Storage Temperatures
– -50 to 200 Degrees F
• 5 to 95% relative humidity, non-condensing

Mounting the Remote Human
Interface Panel
All mounting hardware such as hand tools, electrical
boxes, conduit, screws, etc. are to be field provided. Refer
to
Figure 2, p. 7 for the location and configuration of the
mounting holes, electrical access knockouts in the back
and ends of the enclosure.
Mounting the Remote Panel on a four-by-
four inch Electrical Handy Box
Refer to Figure 2, p. 7 while following the steps below for
mounting the Remote Panel on a 4 x 4 electrical handy box.
1. Place the microprocessor in a clean dry location during
the enclosure mounting procedures to prevent
damage.
2. Mount an electrical handy box in the wall so that the
front edge of the box will be flush with the finished wall
surface.
Prior to mounting the panel, the microprocessor module
must be carefully removed from the enclosure. To remove
the module:
a. Lay the Remote Panel face up on a flat surface and
remove the locking screw from the right hand
bottom end of the panel.
