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.

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 unit.
•
Keep top and bottom air vents clear at all times.
•
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 par ts
of the dimmer.
•
Each dimming circuit must have a separate neutral connection.
•
All electrical ratings are for continuous duty.
•
AC lighting loads only.
