Radia Lighting Control System
The RDA-ENC2 enclosure contains a ground-terminating lug. The RDA-ENC4, RDA-ENC6,
RDA-ENC6B, and RDA-ENC12B enclosures contain a neutral terminating block and a ground-
terminating lug.
Low-Voltage Connections
The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for
AXlink, PROlink, dry closures, and module jack connectors. On the controller cards, low-voltage
power for the board is supplied either by line power, optional auxiliary power supply (RDA-PSM),
or the +12 VDC pin on the AXlink connector. There is also a green status LED on the controller
circuit board that blinks, according to the current operating status of AXlink and red LEDs, one for
each of the external connectors for additional modules. Figure 18 shows an example of the low-
voltage connections, DIP switches and LEDs using the RDD-DM4 controller.
