5. Setup and Installation
5.1 Wiring Instructions
Before starting, ensure the main power supply is OFF at the circuit breaker to prevent electrical shock.
- Identify Wires: Locate the Live (L), Neutral (N), and Load (L1, L2) wires for your existing switch.
- Connect Input: Connect the AC-IN N terminal of the smart module to the Neutral wire and the AC-IN L terminal to the Live wire.
- Connect Output (1 Gang): For a single gang setup (SW02-01), connect the L1 terminal to the load (e.g., light bulb) and the K1 terminal to your traditional switch.
- Connect Output (2 Gang): For a two gang setup (SW02-02), connect L1 and L2 terminals to their respective loads, and K1 and K2 terminals to your traditional two-gang switch.
- Secure Connections: Ensure all wire connections are tight and properly insulated.
- Mount Module: Carefully place the mini smart switch module into the wall box behind your traditional switch.
- Restore Power: Turn the main power supply back ON.
