RDA-CKM Dual Choke Module
The RDA-CKM Dual Choke Module is used for debuzzing, lamp noise
reduction, and to correct minor common neutral interactions. This unit con-
sists of dual 350 µS rise time chokes. It occupies only one enclosure space
and is useful with the RDD-DM series of integrated dimmer modules. The
module's 120 and 240-277 VAC ratings are 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
of the dimmer.
• Each dimming circuit must have a separate neutral connection.
• All electrical ratings are for continuous duty.
• For indoor use only.
• AC lighting loads only.
