DTP HDMI 230 & 330 D Transmitter and Receiver • Installation and Operation 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, use the Decora Template
Dimensions on page 15 to create a template. If installing directly into furniture, cut out
the center portion of the template.
2. Place the wall box (or the full-sized 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.
