RDM-INC Incandescent Dimmer Module  
2400 W  
The RDM-INC Incandescent Dimming Module is designed for use with the  
RDA series of enclosures, in a AMX Lighting™ modular digital dimming  
system. It is a standard 2400 W incandescent dimmer. It can dim incandes-  
cent lights, cold-cathode, neon and two-wire dimmable ballasts. The RDM-  
INC module's 120, 240, and 277 VAC ratings are CE, UL, and C-UL  
approved.  
Test loads for shorts before connecting.  
Use low voltage wires with a 300 volt rating or greater.  
Use field installed copper conductors.  
Run all low-voltage and control wires away from heat producing parts  
of the dimmer.  
Each dimming circuit must have a separate neutral connection.  
All electrical ratings are for continuous duty.  
AC lighting loads only.  
Mounting  
points  
For indoor use only.  
This module may require extra power from the AXlink connection or an  
external power supply connected to the control card.
