UL and Safety Guidelines
The following UL guidelines pertain to the installation of the decorator-style wallplate
decoders into a wall or furniture.
•
These units are not to be connected to a centralized DC power source or used beyond
their rated voltage range.
•
These units must be installed in UL-listed junction boxes.
•
These units must be installed with conduit in accordance with National Electrical Code.
Choosing and Preparing the Site
Choose the site
Choose a location that allows cable runs without interference. Allow enough depth for
both the wall box and the cables. The box should be at least 3.0 inches (7.6 cm) deep
to accommodate the connectors and cables. Install the cables into the wall, furniture, or
conduits before installing the encoder.
The encoder fits into a standard US three-gang junction box or mud ring and includes a
decorator-style wallplate and a metal mud ring. Optional UL Listed junction boxes, external
junction boxes, and surface mounting boxes are available for use with the unit. Please
see the product specifications, available on the Extron website,
for the
product dimensions.
NOTE:
The encoder is wider than a standard 3-gang device. You cannot install
another wall-mounted device immediately adjacent to this device.
Americans with Disabilities Act (ADA) compliance
When planning where to install the encoder, you may need to consider factors affecting
accessibility of the encoder such as height from the floor, distance from obstructions,
and how far a user must reach to access the connectors. For guidelines, see sections
307 (“Protruding Objects”) and 308 (“Reach Ranges”) of the
2010 ADA Standards for
Accessible Design
