4. Installation and Setup
The RF9540-NDW dimmer is designed to fit into standard wallboxes and utilizes existing 120V/AC 60Hz standard house wiring. A neutral wire is required for installation.
4.1 Wiring Requirements
- Voltage: 120V AC, 60Hz
- Load Compatibility: Incandescent, MLV, ELV, LED, CFL, FLR (600W max for INC/ELV/FLR, 300W max for LED/CFL, 500VA for MLV)
- Neutral Wire: Required for operation.
4.2 Installation Steps
- Turn Off Power: Locate the circuit breaker or fuse that supplies power to the switch you are replacing and turn it OFF. Verify power is off using a voltage tester.
- Remove Existing Switch: Carefully remove the wall plate and unscrew the existing switch from the wallbox. Disconnect the wires.
- Identify Wires: Identify the Line (hot), Load, Neutral, and Ground wires. The RF9540-NDW requires a neutral wire.
- Connect Wires:
- Connect the dimmer's Line wire to the Line (hot) wire from the wallbox.
- Connect the dimmer's Load wire to the Load wire leading to the light fixture.
- Connect the dimmer's Neutral wire to the Neutral wire from the wallbox.
- Connect the dimmer's Ground wire to the Ground wire from the wallbox.

5. Operation
The RF9540-NDW dimmer offers both manual and remote control capabilities.
5.1 Manual Control
- On/Off: Press the large electro-mechanical push pad to turn the connected lights ON or OFF.
- Dim/Bright: Use the separate dim/bright bar located next to the push pad to adjust the light level. Press the top of the bar to brighten and the bottom to dim.
- Full Brightness: Press and hold the main push pad for 2 seconds to bring the lights to full brightness, regardless of any preset levels.
5.2 LED Display
A seven-step blue LED display is located alongside the push pad. This display indicates the selected light level. When the lights are off, the LEDs reduce brightness, functioning as a nightlight feature.
5.3 Remote Control (Z-Wave)
The dimmer can be controlled remotely by commands sent from an Aspire RF Controller (e.g., RFTDCSG, RFHDCSG, RFTCP) or other Z-Wave compatible controllers or programs. Refer to your Z-Wave controller's instructions for pairing and remote operation.
6. Programming Features
When used with Aspire RF or other Z-Wave compliant controllers, the RF9540-NDW dimmer supports various programmable functions:
- Scenes: Integrate the dimmer into custom lighting scenes.
- Events: Trigger lighting changes based on specific events.
- Association: The dimmer can be associated with up to 5 other Z-Wave devices for synchronized control.
- Child Lockout: A programmable feature to prevent unauthorized operation.
- Rapid and Delayed Fading: Customize the fade-up and fade-down times for lights. The default setting is 10 seconds, with options up to 4 minutes.
- Adjustable Low-Level Trim: Helps prevent flickering with certain lighting loads by setting a minimum dimming level.
- Adjustable High-Level Trim: Allows for additional energy savings by setting a maximum dimming level.
- Programmable Rapid Start: Ensures lamps start up reliably even at low dimming levels.
7. Maintenance
The Eaton RF9540-NDW dimmer requires minimal maintenance.
- Cleaning: To clean the device, wipe it with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the finish or internal components.
- Air-Gap Switch: The dimmer features an air-gap switch that disconnects power from the load, forcing an off condition. This can be used for maintenance or to completely de-energize the circuit for safety.
