Installation Sheet

RDM-HDC Heavy Duty DC Module 2400 W, 0-12 VDC

The RDM-HDC Heavy Duty DC Module is a heavy-duty 2400 W module for dimming of fluorescent ballast loads. It uses a 0 to 12 VDC current sinking or sourcing for use with all 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, 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.

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

• Use field installed copper conductors.
