DTP DVI 230 D Transmitter and Receiver • Introduction 4
To install a new wall box, perform steps 1 through 9. If a suitable wall box is already 
installed, perform steps 6 through 9 on the next page. UL listed wall boxes are 
recommended.
1.  If a wall box is not available to use for a template, see Decora Template Dimensions 
on page 15 to create a template. If installing directly into furniture, cut out the center 
portion of your template.
2.  Place the wall box (or your template) against the installation surface, and mark the 
opening guidelines.
3.  Cut out the material from the marked area.
4.  Insert the wall box into the opening. The rear connectors on the box or wall plate should 
fit easily into the opening. Enlarge or smooth the edges of the opening if needed.
5.  Secure the wall box with nails or screws, leaving the front edge flush with the outer wall 
or furniture surface (see figure 2).
NOTES: 
•  If attaching the wall box to wood, use four #8 or #10 screws or 10-penny 
nails. A minimum of 0.5 inch (1.3 cm) of screw thread must penetrate the 
wood.
•  If attaching the wall box to metal studs or furniture, use four #8 or #10 
self-tapping sheet metal screws or machine bolts with matching nuts.
