4. Setup and Installation

4.1 Electrical Installation

1. Disconnect Power: Before starting, ensure the main power supply to the circuit is turned off at the circuit breaker.
2. Identify Wires: Locate the Live (L) and Neutral (N) wires for power input, and the motor control wires (typically Open, Close, and Common/Neutral for the motor).
3. Connect Power Input: Connect the Live (L) wire from your power supply to the 'L' terminal on the module and the Neutral (N) wire to the 'N' terminal on the module.
4. Connect Motor:
   • For a single motor with Open/Close: Connect the motor's 'Open' wire to L1, 'Close' wire to L2, and the motor's Neutral/Common to L. (Refer to Figure 1 for L, N, L1, L2, L3, L4 connections).
   • For two independent motors: Connect Motor 1's Open to L1, Close to L2. Connect Motor 2's Open to L3, Close to L4. Ensure both motors share a common Neutral connected to the 'L' terminal on the module (as per diagram, 'L' is common for motor outputs).
5. Connect External Switches (Optional): If using traditional physical switches, connect them to S1, S2, S3, S4 terminals as per your desired configuration. S1/S2 typically control L1/L2, and S3/S4 control L3/L4.
6. Secure Module: Place the module securely within the switch box or junction box, ensuring no wires are pinched.
7. Restore Power: Turn the main power supply back on.

4.2 App Pairing (Tuya Smart / Smart Life)

1. Download App: Download the "Tuya Smart" or "Smart Life" app from your smartphone's app store (iOS or Android).
2. Register/Login: Open the app and register for a new account or log in to an existing one.
3. Enter Pairing Mode: After powering on the module, it should automatically enter pairing mode (indicated by a rapidly blinking indicator light, if present). If not, press and hold the reset button (if available, or the connected physical switch for 5-10 seconds) until the indicator blinks rapidly.
4. Add Device: In the app, tap the '+' icon in the top right corner to add a device. Select "Curtain Switch" or "Curtain Module" from the device list.
5. Confirm Blinking: Confirm that the indicator light is blinking rapidly in the app.
