5. Setup
5.1. Pre-Installation Checklist
- Ensure you have a neutral wire (usually white) in your electrical box.
- Confirm your existing switch is a single-pole or 3-way configuration.
- Verify your bulbs are dimmable LED, CFL, or incandescent.
- You will need a 2.4GHz Wi-Fi network.
5.2. Wiring Instructions
IMPORTANT: Always turn off power at the circuit breaker before beginning any electrical work.
5.2.1. Single Pole Wiring Diagram
Image Description: This diagram illustrates the wiring for a single-pole setup of the Nexete Smart Wi-Fi Dimmer Switch. It shows connections for Live (black), Neutral (white), Load (red/black), and Ground (green) wires. The YL/RD (traveler) wire should be capped off and insulated for single-pole use. A caution advises to use this product with a 4A circuit breaker upstream.
For single-pole installations, connect the wires as follows:
- Live Wire: Connect to the Live terminal on the switch.
- Neutral Wire: Connect to the Neutral terminal on the switch.
- Load Wire: Connect to the Load terminal on the switch.
- Ground Wire: Connect to the Ground terminal on the switch.
- YL/RD (Traveler) Wire: For single-pole use, this wire must be capped off and insulated.
5.2.2. 3-Way Wiring Diagram (Replacing One Switch)
Image Description: This diagram illustrates a 3-way wiring setup where one traditional switch is replaced with the Nexete Smart Wi-Fi Dimmer Switch. It shows how to use an unused traveler wire to bring live power to the load side for the smart switch. The diagram highlights the connections for Live, Neutral, Load, and Traveler wires, emphasizing that the smart switch requires both Live and Neutral wires.
For 3-way installations, where you replace one existing 3-way switch with the smart dimmer, a creative use of an unused traveler wire is often required to deliver live power to the smart switch. Refer to the diagram carefully and ensure all connections are secure. The smart dimmer should be installed on the load side if the load side did not have live power, using one traveler to connect power for the live wire.
5.2.3. 3-Way Wiring Diagram (Two Smart Dimmers)
Image Description: This diagram shows a 3-way wiring setup utilizing two Nexete Smart Wi-Fi Dimmer Switches. It details the connections for Live, Neutral, Load, and Traveler wires for both switches, indicating that both smart dimmers require Live and Neutral wires for proper operation.
If installing two smart dimmers in a 3-way circuit, ensure both switches receive a Live and Neutral connection. Follow the diagram for proper traveler wire connections between the two smart switches.
