4. Wiring and Installation
Proper wiring is crucial for safe and effective operation. Always ensure power is disconnected before performing any wiring. The receiver supports AC85V-240V input and provides an output that matches the input voltage.
4.1 Basic Connection Diagram:
The receiver has clearly labeled terminals for AC Input (L, N) and AC Output (L, N). Connect your power source to the AC Input terminals and the appliance you wish to control to the AC Output terminals.
Image 4.1: Examples of easy wiring connections for common household appliances such as electric fans, lanterns, water pumps, and coffee makers. The diagram shows connecting the Line (L) and Neutral (N) wires from the power source to the receiver's input, and then from the receiver's output to the appliance.
4.2 Motor Wiring (Inductive Loads):
For inductive loads, such as pump motors larger than 600W, it is recommended to use an AC contactor. This helps manage the large starting current and voltage fluctuations associated with motors, protecting the relay switch.

4.3 Various Applications:
The remote control relay switch can be integrated into various systems for wireless control. Examples include:
- Controlling lighting fixtures.
- Operating exhaust fans or other ventilation equipment.
- Managing water pumps for irrigation or water storage.
- Controlling industrial machinery within its power limits.
