Radia Lighting Control System
Installation
Space Requirements
AMX Lighting control installations require very little space. Enclosures are the main concern. All
enclosures are mounted flush, on a vertical surface and must have a minimum clearance of 12"
(304.8 mm) above and below to allow for air circulation. Physical dimensions for each enclosure
are described in the Installation section.
Conduit
Conduit runs depend on the enclosures you use and their AMX Lighting modules. All enclosures
have conduit knockouts on the top for high-voltage connections, and knockouts on the bottom for
low-voltage connections.
All conduit knockouts allow for 1/2, 3/4, and 1-inch (12.7 mm, 19.0 mm, and 25.4 mm) conduits as
shown in FIG. 3. You should also consider these recommendations prior to installing enclosures:
Install separate conduit for lighting loads. The recommended knockout for loads is
located on the top center of the enclosure.
Install separate conduit for the 120 VAC wiring to the line input terminal block. The
recommended knockouts for incoming power feeds are located on the top-left and top-
right sides of the AMX Lighting enclosure.
Install separate conduit for low-voltage signals for dry closures, AXlink, and PROlink connections.
The recommended knockout for these control connections is located on the bottom of the
enclosure. There are additional knockouts on the bottom-left and bottom-right sides of the
enclosures for alternate low-voltage connections.
