FIG. 3 RDM-ZC50 wiring configuration

•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.

•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.

•AC lighting loads only.

•For indoor use only.

•This module may require extra power from the AXlink connection or an external power supply connected to the control card.
