4. Installation and Setup
IMPORTANT: Installation should only be performed by a qualified electrician in accordance with all applicable electrical codes.
- Power Disconnection: Before beginning any work, ensure the main power supply to the circuit is completely disconnected at the service panel. Verify with a voltage tester.
- Mounting: Mount the smart circuit breaker onto a standard DIN rail within an appropriate electrical enclosure.
- Wiring:
- Connect the incoming Neutral (N) wire to the 'N Power' terminal.
- Connect the incoming Live (L1) wire to the 'L1 Power' terminal.
- Connect the outgoing Neutral (N) wire to the 'N Load' terminal.
- Connect the outgoing Live (L1) wire to the 'L1 Load' terminal.
- Ensure all screw terminals are tightened securely to prevent loose connections and overheating.
- Power Restoration: Once wiring is complete and verified, restore power to the circuit.
- WiFi Pairing:
- Download the compatible smart home application (e.g., Ewelink) on your smartphone.
- Follow the in-app instructions to add a new device. This typically involves putting the circuit breaker into pairing mode (often by pressing and holding the 'e' button or cycling power) and connecting it to your 2.4GHz WiFi network.
- Once paired, the signal light on the device will indicate a successful connection (e.g., solid blue).
5. Operating Instructions
After successful installation and WiFi pairing, you can operate your smart circuit breaker using the dedicated smartphone application.
5.1 Remote Control
- Open the smart home application on your smartphone.
- Select your TOMZN Smart Circuit Breaker from the device list.
- Use the on-screen controls to remotely turn the circuit breaker ON or OFF.
5.2 Energy Monitoring
- Within the device interface in the app, navigate to the energy monitoring section.
- View real-time data for voltage (V), current (A), power (W), and total energy consumption (kWh).
- Historical data and consumption reports may also be available depending on the application features.
5.3 Timer and Schedule Functions
- Access the timer or schedule settings for your device in the application.
- Set up custom schedules for automatic ON/OFF operations based on time of day or day of the week.
- Utilize countdown timers for temporary control.
5.4 Voltage and Amperage Protection (TOB9e-63M only)
For the TOB9e-63M model, the application may allow you to set thresholds for over-voltage, under-voltage, and over-current protection. If these thresholds are exceeded, the circuit breaker will trip to protect connected appliances and the electrical system.
