RDM-MDM Multimode Dimmer Module 2400 W

The RDM-MDM Multimode Dimmer Module is ideally used in situations where the load is not specified or the load may change at the last moment. This unit is a unique combination 2400 W Incandescent dimmer,

2400 W Switch, or 2400 W FDB fluorescent dimmer. It consists of a heavy duty SSR construction for dimming and a heavy duty positive air gap relay for switching. The RDM-MDM module's 120 and 240-277 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.

• 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
