6. Installation (Setup)

The eMylo Smart Circuit Breaker is designed for easy installation on a standard 35mm DIN rail. Follow these steps carefully:

1. Power Disconnection: Before starting any electrical work, ensure the main power supply to the circuit is completely disconnected at the main breaker or fuse box. Use a voltage tester to confirm the power is off.
2. Mounting: Locate a suitable 35mm DIN rail within your electrical panel. Align the circuit breaker with the rail and press firmly until it clicks into place. Ensure it is securely mounted.
3. Wiring:
   • Connect the incoming live wire (L) from your power source to the "L power" terminal on the top of the circuit breaker.
   • Connect the incoming neutral wire (N) from your power source to the "N power" terminal on the top of the circuit breaker.
   • Connect the outgoing live wire (L) to your load (appliance/circuit) to the "L load" terminal on the bottom of the circuit breaker.
   • Connect the outgoing neutral wire (N) to your load (appliance/circuit) to the "N load" terminal on the bottom of the circuit breaker.
   • Ensure all wire connections are tight and secure to prevent loose connections and potential hazards.
4. Power Restoration: Once all wiring is complete and verified, restore power to the circuit at the main breaker. The device's indicator light should illuminate.
