Wiring Diagrams

WARNING: Please install and maintain the device by a professional electrician. To avoid an electric shock hazard, do not operate any connection or contact the terminal connector while the device is powered on! The product is designed to be completely installed into a flush-mounted box and enclosed with a cover plate or switch that fulfills the corresponding national standard requirement. There shall be no exposure of any part of the product after installation. Diameter of wiring(recommend):16AWG to 14AWG SOL/STR copper conductor only. No matter S1 and S2 are connected or left idle to the external switch, this device can be controlled by automation or the App. It is prohibited to connect S1 and S2 terminals to the neutral or ground wire, in order to avoid damaging the equipment and causing danger. To ensure the safety of your electrical installation, it's essential that either a Miniature Circuit Breaker (MCB) or a Residual Current operated Circuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 10A has been installed before the MINIR4. Make sure all wires are connected correctly.
