ATTENTION: Installation and service must be performed by experienced personnel.
The DTP HDMI 230 & 330 D transmitters and receivers can be installed in a two-gang
electrical wall box, or with a mud ring, with a Decora wall plate cover (supplied).
The installation must conform to national and local building, electrical, and safety codes and
to the size requirements of the wall plate.
UL and Safety Guidelines
The following UL guidelines pertain to the installation of the Decora transmitters and
receivers 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 wall boxes.
• These units must be installed with conduit in accordance with National Electrical Code.
Site Preparation and Wall Box Installation
Choose a location that allows cable runs without interference. Allow enough depth for both
the wall box and the cables. Install the cables into the wall, furniture, or conduits before
installing the wall plate.
NOTE: The Decora units are very deep and have connectors on the back side. Extron
recommends a 2-gang wall box which has a depth of at least 3.0 inches (7.6 cm) to
accommodate the connectors and cables.
