Mounting the MLC to an electrical box or mud ring
1.
With power disconnected at the source, insert the MLC into the wall or
furniture.
2.
Mount the MLC to the wall box or mud ring mounting bracket with the
provided machine screws (mounting screws, as shown in the following
illustrations).
N If the MLC (and any accessories such as control modules or an IR Link) is not
mounted to a grounded metal wall box,
• Ground each faceplate directly to an earth ground. Or...
• Tie each faceplate to its circuit board and power supply via a ground pin on
one of the connectors.
Do not tie a product’s faceplate to both a separate earth ground and the circuit
ground (via a connector pin). If you tie a product to two different ground
sources, you may introduce ground
loops or other grounding-
related problems into the
system.
N For the installation to
meet UL requirements
and to comply with
National Electrical Code
(NEC), the MLC must
be installed in a UL
approved junction box.
The end user or installer
must furnish the junction
box; it is not included
with the MLC.
