MLC Plus 50/100/200 Series • Hardware Features and Installation 12
Site Preparation
Mud rings, optional ULListed junction
boxes, external junction boxes,
and surface mounting boxes are
available for use with the MLCPlus.
Read any installation instructions
and UL guidelines that come with
the mounting devices, protect the
mounting surface to prevent
damage, then install the box
or mud ring in the opening at
the installation site.
The following table provides the approximate sizes of holes to cut in the installation surface
depending on the gang size of the device and whether you are using the provided mud ring
or attaching the MLCPlus directly to the mounting surface.

When you run cables to the mounting location, leave enough slack for device installation.
Secure the cables with a clamp for strain relief so they do not slip back down into the wall or
furniture.
Installation Step 3: Change a Faceplate or Button Labels (Optional)
Faceplates can easily be changed, if desired. Or you can replace one or more of the
labels within the buttons. Some button labels ship with the unit. You can create and print your
own customized labels using Extron Button Label Generator software, available free from
www.extron.com.
Replacing a Faceplate
To replace a faceplate prior to installation:
1. Remove the faceplate by holding the body of the unit with one hand, gripping the sides
of the faceplate with the other hand, and pulling the faceplate away from the unit.

Changed cm to mm.

do not need additional
levels of precision (such as
hundredths of inches) for
these dimensions.
