MLM 52 Wall Mounting Kits • Installation 5
1. If a wall box is not available for marking the mounting hole, create a full-scale
template with the dimensions shown in the “
Templates and Dimensions ” section
(beginning on page 7). Cut out the center portion of the template you created.
2. Place the template (or the wall box) against the installation surface, and mark the
opening on the wall or furniture.
3. Cut out the material from the marked area.
4. Check the size of the opening by inserting the wall box into it. The box should fit
easily. Enlarge or smooth the edges of the opening if needed.
5. Feed cables through the wall box punch-out holes and secure them with cable clamps
to provide strain relief.
6. Exposed cable shields (braids or foil) are potential sources of short circuits. Trim back
the shields or insulate them with heat shrink.
7. Insert the wall box into the opening and attach it to the wall, stud, or furniture with
nails or screws, leaving the front edge flush with the outer wall or furniture surface
(see figure 5).

Figure 5. Installing One-gang and Two-gang Wall Boxes
• If attaching the wall box to wood, use four #8 or #10 screws or 10-penny nails. A
½ inch (1.3 cm) minimum of screw threads 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.
8. Cable and test the controller before fastening it into the wall box. The cables will be
inaccessible after installation.
Installing a Mounting Bracket
One-gang or two-gang Decora ® style mounting brackets are provided with the
MLC 52 controller. If desired, you can mount the controller and the MLM 52 faceplate to
this type of bracket instead of to an electrical box as follows:
1. If desired, create a full-scale template with the dimensions shown in the “ Templates
and Dimensions ” section (beginning on page 7). Cut out the center portion of the
template you created.
2. Use the template you created in step 1 or the dimensions shown on pages 8 and 9 to
mark the opening on the mounting surface.
3. Cut out the material from the marked area.
4. Insert the bracket into the hole.
