12 RE-DM4 and RE-DM6 RADIA Eclipse Dimmer Modules
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. 11.
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 and AxLink connections. The
recommended knockout for these control connections is located on the bottom of the enclosure.
 Additional knockouts are on the bottom-left and bottom-right sides of the enclosures for alternate
low-voltage connections.
