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.
