PRELIMINARY
Mounting the MLC to an electrical box or mud ring
With power disconnected at the source, 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.
