RDM-INC50 Incandescent Dimmer Module
6000 W
The RDM-INC50 Incandescent Dimmer Module is a standard 6000 W
incandescent dimmer. It can dim incandescent lights, cold-cathode, neon
transformers and two-wire dimmable ballasts. It is designed for use with the
RDA series of enclosures, in a AMX Lighting™ modular digital dimming
system. The RDM-INC50 module's 120, 240, and 277 VAC ratings are CE,
UL, and C-UL approved.

Caution: Pre-Installation Notes
• All Class 1 wiring must be connected to proper terminals.
• All control wiring must be connected to proper terminals.
• Disconnect power while installing or connecting the unit.
• Keep top and bottom air vents clear at all times.
• Test loads for shorts before connecting.
• Run all control and low-voltage wires away from heat producing parts
of the dimmer.
• Each dimming circuit must have a separate neutral connection.
• Use low-voltage wires with a 300 volt rating or greater.
• Use field installed copper conductors.
• All electrical ratings are for continuous duty.
• AC lighting loads only.
• For indoor use only.
• This module may require extra power from the AXlink connection or an
external power supply connected to the control card.
