Figure 53. Attaching an Electrical Box to a Wall Stud
• If you are attaching the wall box to wood, use four #8 or #10 screws or 10-penny
nails. A minimum of ½ inch (1.3 cm) of screw threads must penetrate the wood.
• If you are 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.
• If you are using a mounting bracket (mud ring) with the electrical box, see
Mounting the MLC to a Decora Mounting Bracket on page 25 to attach the
clips that fasten the bracket to the wall or furniture.
9. Ground the MLC to the electrical box as follows:
a. Attach the bare wire end of the provided grounding wire to the Gnd pin of the
6-pole captive screw connector on the MLC rear panel.
b. Attach the other end of the grounding wire to a screw on the junction box.
10. If desired, replace the faceplate or button labels on the MLC (see Replacing the
Faceplate (US Models Only) on page 9 or Replacing Button Labels on page 10).
11. Cable and test the MLC before fastening it into the wall box, mounting bracket, or
furniture.

bracket. You do not need the templates if you are mounting the panel using an external
mounting option.

• These templates are not to scale and are provided for reference only.
The MLC controller requires a depth of at least 1.25 inches (3.2 cm) inside the wall or
