Installation Guide

RDM-2DC Dual DC Dimmer Module 1920W, 0-10 VDC (x2)

The RDM-2DC Dual DC Module (FG606-61) is a 1920 W module used for the dimming of fluorescent ballast loads. It uses a 0 to 10 VDC current sinking for use with four-wire ballasts. It is designed for use with the RDA series of enclosures, in an AMX Lighting™ modular digital dimming system. The module’s 120 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.

Low-voltage control wiring: 4-pin connector to AMX Lighting master controller

• Use low-voltage wires with a 300 volt rating or greater.

• Use field installed copper conductors.

• All electrical ratings are for continuous duty.

• For indoor use only.

• Test loads for shorts before connecting.

• This module may require extra power from the AXlink connection or an

external power supply connected to the control card.

	The fuses protect the dimming
	circuit from a low impedance load.
	• The fuse will blow if it were
		incorrectly wired
	•	Catastrophic ballast failure
Circuit breaker	•	Reversing switched and
panel		dimmed circuits
	•	Reversing dimmed and
		line circuits.

The dimmed output must be connected to a high impedance load.
