4. Setup and Installation

IMPORTANT: Ensure all power is disconnected at the main breaker before proceeding with installation.

4.1 Mounting

The Walfront Smart WiFi Circuit Breaker is designed for panel mounting. Secure the device firmly within an appropriate electrical panel or enclosure.

Figure 3: Installation size diagram, providing dimensions for mounting the circuit breaker (e.g., 72mm for 3P, 54mm for 2P).

4.2 Wiring

1. Connect the AC220V main power supply wires to the 'INPUT' terminals of the circuit breaker.
2. Connect the load circuit wires to the 'OUTPUT' terminals of the circuit breaker.
3. Ensure all connections are secure and properly insulated.
4. Double-check all wiring for correctness before restoring power.

4.3 WiFi Pairing

To enable remote control functionality, the circuit breaker must be paired with the mobile application.

1. Download the designated mobile application (refer to the packaging or product documentation for app name).
2. Ensure your mobile device is connected to a 2.4GHz WiFi network.
3. Power on the circuit breaker. The WiFi indicator light will typically flash, indicating pairing mode.
4. Open the mobile application and follow the on-screen instructions to add a new device.
5. Confirm successful pairing when the WiFi indicator light becomes solid.

5. Operation

5.1 Manual Operation

• To turn the circuit ON, push the manual switch lever(s) upwards to the 'ON' position.
• To turn the circuit OFF, pull the manual switch lever(s) downwards to the 'OFF' position.

5.2 Remote Control via APP

Once paired, you can control the circuit breaker remotely using the mobile application:

1. Open the mobile application on your smartphone.
2. Select the Walfront Smart WiFi Circuit Breaker from your device list.
3. Use the virtual ON/OFF button within the app to switch the circuit remotely.

5.3 Overcurrent Trip Mechanism

The circuit breaker is equipped with an overcurrent trip mechanism. In the event of an overcurrent condition, the breaker will automatically trip to the 'OFF' position, protecting the circuit from damage. To reset after a trip, resolve the overcurrent cause, then manually switch the breaker back to the 'ON' position.

5.4 Mechanical Lock for Safety

The circuit breaker includes an anti-misclosing mechanism and a safety lock feature. This mechanism ensures that the circuit breaker remains in the open (OFF) position when the safety lock is engaged, preventing accidental closure during maintenance or repair.

Figure 5: Illustration of the mechanical lock mechanism. Pulling out the safety lock keeps the breaker in the open position. Pushing it in unlocks the mechanism.

To engage the safety lock: Pull out the designated safety lock tab. The circuit breaker will then remain open and cannot be closed. To disengage and reset: Push the safety lock tab back into its original position.

6. Maintenance

• Regularly inspect the circuit breaker for any signs of physical damage, loose connections, or discoloration.
• Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Ensure proper ventilation around the circuit breaker to prevent overheating.
• If any issues are detected, disconnect power immediately and consult a qualified electrician.

7. Troubleshooting

7.1 Circuit Breaker Does Not Turn On

• Check if the main power supply is active.
• Ensure the safety lock mechanism is disengaged.
• Verify that there is no overcurrent or short circuit in the connected load.

7.2 WiFi Connection Issues

• Ensure the circuit breaker is powered on and the WiFi indicator is flashing (for pairing) or solid (for connected).
• Verify your mobile device is connected to a 2.4GHz WiFi network.
• Check the distance between the circuit breaker and your WiFi router. Move closer if necessary.
• Restart your WiFi router and attempt pairing again.
• Confirm the correct WiFi password is being entered in the app.

7.3 Circuit Breaker Trips Frequently

• An overcurrent condition is likely present. Reduce the load connected to the circuit.
• Inspect the wiring for any short circuits or damaged insulation.
• If the issue persists after reducing the load and checking wiring, the circuit breaker may be faulty or incorrectly rated for the application. Consult a qualified electrician.
