Mounting the Remote Human
Interface (RHI) Panel
The installer must provide all mounting hardware such as;
hand tools, electrical boxes, conduit, screws, etc. Refer to
Figure 32, p. 47 for the mounting hole and knockout
locations.
Procedure
Refer to Figure 32, p. 47 and follow the procedure below
for mounting the remote HI panel on a 4” by 4” electrical
junction box. Place the microprocessor in a clean dry
location during the enclosure mounting procedures to
prevent damage.
1. Mount an electrical junction box in the wall so that the
front edge of the box will be flush with the finished wall
surface.
2. 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
remo
ve the locking screw from the right hand
bottom end of the panel.
b. Remove the recessed hinge screw from the left
hand bottom end of the panel.
c. Unlatch the door of the enclosure as if to open it,
and slide the left hand side of the door upward away
from the hinge. Lay it aside.
d. With the key pad visible, remove the two (2) screws
located on the right hand side of the key pad.
e. Carefully slide the key pad plate upward from the
bottom, releasing the extruded hinge pin from its
socket at the top.
f. Set the microprocessor aside until mounting is
complete.
3. Remove the junction box knockout in the back of the
enclosure.
Note: The
top of the enclosure is marked “TOP.”
4. With the enclosure in the correct position; align the
mounting
holes around the knockout in the enclosure
with the screw holes in the electrical handy box and
secure with the appropriate screws.
5. Replace the microprocessor within the enclosure as
follows:
a. Verify that the terminal block jumpers are
connected
properly.
b. Slide the extruded hinge pin at the top left of the key
pad plate into the hole located at the top left hand
side of the enclosure.
c. Slide the bottom of the plate into place, aligning the
two (2) clearance holes with the screw holes on the
right. Install the screws but do not tighten.
Note: If the two screws are not installed as called out in
the previous step, hold against the key pad plate
while installing the door in the next step, to prevent
it from falling out.
d. Slide the extruded hinge pin at the top left of the
door into the hole located under the bottom left side
of the display.
e. Install and tighten the hinge screw located at the
bottom left side of the enclosure.
Wall Mounting the RHI Panel
1. Prior to mounting the panel, the microprocessor
module must be removed from the enclosure.
Complete step 2 in the previous discussion,“Mounting
on a 4 in. x 4 in. Electrical Box,” before proceeding.
2. With the microprocessor removed, refer to Figure 32,
p. 47 for the location of the mounting holes to be used
for wall mounting.
3. Place the enclosure against the mounting surface and
mark
the mounting holes.
Note: The
top of the enclosure is marked with “TOP.”
4. With the enclosure in the correct position, remove the
enclosure
and drill the necessary holes in the surface
for the appropriate fasteners, (plastic anchors, molly
bolts, screws, etc.)
5. Remove the necessary knockouts for the wire or
conduit
entry before mounting the panel.
6. Place the enclosure back onto the surface and secure it
with
the appropriate screws.
7. Follow step 5 in the previous section, “Mounting on a
4”
by 4” Electrical Box,” to replace the microprocessor
within the enclosure.
