BOARD INSTALLATION
Inside the can, several 2-holed insertion points have been
constructed. This allows for either vertical or horizontal placement of
the modules. Notice that each insertion point has two sizes of holes -
a larger hole and a smaller hole.
Diagram 1
: The black plastic PCB guides are grooved on one edge
where the PC board will be seated. The end with the half-moon
protrusion fits into the larger hole. The smaller hole is for the screw.
Diagram 2
: Place the first black plastic PCB guide in the top insertion
point, grooved edge downward. The half-moon protrusion will be in
the large hole. It does not require force. Insert one of the provided
screw into the smaller hole (from inside the can) to secure it in place.
A screwdriver should reach through the notch that runs the length of
the guide to tighten the screw. The second PBC guide should be
positioned opposite the first (grooved edge up) and placed in the
lower insertion point, using the same procedures described above.
Once mounted, screw it in securely.
Diagram 3
: The PC Board should slide freely in the grooves of both
guides.
