Required Tools and Components
NOTE: The plaster ring external mounting face must
be positioned flush to recessed, relative to the
surface of the wall. Also note the orientation
of the four mounting screws in the plaster
ring, as the plaster ring is rotated 90° from
conventional mounting.
In the following wiring sections,
abbreviations are used, such as, J1, P3.
• Flat-head screwdriver
• (1) Double gang metal electrical box with
grounding stud
• (1) 4 × 4-inch metal plaster ring
• (1) Door switch SPDT or SPST, N.O., as
needed

• The safety ground path consists of four 6-32
× 1/2-inch metal screws that connect the
RPM metal base to the 4-1/2 × 4-1/2-inch
metal plaster ring. The plaster ring must be
grounded to the 4-1/2 × 4-1/2-inch electrical
box by two metal mounting screws.

Installation
• The 4-1/2 × 4-1/2-inch electrical box must
be connected to the building earth ground. It
is also highly recommended to use armored
cable (Type AC) for all the wiring in
applications where high levels of radio
interference may be present.
The RPM is designed to be mounted on a standard
double gang metal electrical box using a 4 × 4-inch
plaster ring adapter. Remove the cover and mount
the baseplate to the plaster ring adapter using four
6-32, 1/2-inch long mounting screws.
