5. Tāuta me te Waea
Proper installation is crucial for the safe and effective operation of the MARSTEK Smart Circuit Breaker. Refer to the wiring diagram below and follow all safety precautions.

Hipanga Tāuta:
- Momotu Hiko: Before starting any electrical work, ensure all power to the circuit is completely disconnected at the main service panel. Verify with a voltage Kaiwhakamatautau.
- Whakapiki: Mount the circuit breaker securely in a suitable electrical enclosure or panel. The device is designed for DIN rail mounting or screw mounting.
- Waea Whakauru: Connect the incoming Neutral (N) wire to the terminal marked 'N IN' and the incoming Live (L) wire to the terminal marked 'L IN'.
- Waea Putanga: Connect the outgoing Neutral (N) wire from the terminal marked 'N OUT' and the outgoing Live (L) wire from the terminal marked 'L OUT' to the load you wish to protect.
- Hononga Haumaru: Ensure all terminal screws are tightened securely to prevent loose connections, which can cause overheating or intermittent operation.
- Whakaora Hiko: Once all connections are verified and secure, restore power to the circuit at the main service panel.
6. Operation and Parameter Settings
Upon power-up, the device will display real-time voltage and current. You can adjust the protection parameters to suit your specific needs.
Adjusting Protection Parameters:
- Whakauruhia nga Tautuhinga: Pehia roa te SET button until the display changes, indicating entry into the settings menu.
- Navigate Parameters: Whakamahia te Up (▲) me Ki raro (▼) buttons to cycle through the available parameters (e.g., overvoltage trip value, undervoltage trip value, overcurrent trip value, recovery delay time).
- Tīpakohia te Tawhā: Pehia te SET button briefly to select the currently displayed parameter for adjustment.
- Whakatika Uara: Whakamahia te Up (▲) me Ki raro (▼) buttons to change the parameter's value.
- Whakaū me te Puta: Perehi SET again to confirm the new value and move to the next parameter. To exit the settings menu at any time, long press the SET pātene.
Default Protection Settings:
- Whakawhanatage Haerenga: 140V
- Whakaurutage Haerenga: 90V
- Overcurrent Trip: 63A
- Automatic Recovery Delay: 30 seconds
Automatic Reset Function:
In the event of an overvoltage, whakahekeheketage, or overcurrent condition, the circuit breaker will automatically cut off power to protect the connected load. After a default delay of 30 seconds, the device will attempt to restore power. If the fault condition persists, it will remain disconnected and attempt to reset again after another delay.

- Upon detection of overvoltage, whakahekeheketage, or overcurrent, the circuit is cut off.
- A default delay of 30 seconds begins.
- After 30 seconds, the circuit attempts to reset automatically. If the abnormality is resolved, power is restored. If the abnormality persists, the device continues to wait before another reset attempt.
7. Tiaki
