RADIA Lighting Control System
Mounting AMX Lighting Enclosures
AMX Lighting enclosures must be mounted on a vertical surface with a minimum of 12" (304.8 mm)
clearance above and below the enclosure. FIG. 6 shows the centerline reference points and dimensions.
1. Remove the front cover by removing the screws at the bottom of the enclosure; two tabs suspend the
cover from the top.
2. Position the enclosure on the wall so that it is level, with the high-voltage terminals of the unit at the top.
3. Mark the four mounting holes according to the dimensions shown in Figure 8.
4. Install screws at the marks. The maximum screw size is #12.
5. Hang the enclosure on the four screws. Then, tighten the screws.
Refer to the Dimmer Enclosures with Breakers installation guide for more information.
