5. Enstalasyon ak fil elektrik
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.

Etap enstalasyon:
- Dekoneksyon pouvwa: Before starting any electrical work, ensure all power to the circuit is completely disconnected at the main service panel. Verify with a voltage tèsteur.
- Montaj: Mount the circuit breaker securely in a suitable electrical enclosure or panel. The device is designed for DIN rail mounting or screw mounting.
- Fil elektrik Antre: Connect the incoming Neutral (N) wire to the terminal marked 'N IN' and the incoming Live (L) wire to the terminal marked 'L IN'.
- Fil elektrik Sòti: 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.
- Koneksyon an sekirite: Ensure all terminal screws are tightened securely to prevent loose connections, which can cause overheating or intermittent operation.
- Retablisman pouvwa: Once all connections are verified and secure, restore power to the circuit at the main service panel.

Adjusting Protection Parameters:
- Antre nan Anviwònman: Long peze la SET button until the display changes, indicating entry into the settings menu.
- Navige Paramèt yo: Sèvi ak la Up (▲) ak Desann (▼) buttons to cycle through the available parameters (e.g., overvoltage trip value, undervoltage trip value, overcurrent trip value, recovery delay time).
- Chwazi Paramèt: Peze a SET button briefly to select the currently displayed parameter for adjustment.
- Ajiste Valè: Sèvi ak la Up (▲) ak Desann (▼) buttons to change the parameter's value.
- Konfime epi sòti: Peze 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 bouton.
Default Protection Settings:
- Overvoltage vwayaj: 140V
- Undervoltage vwayaj: 90V
- Overcurrent Trip: 63A
- Automatic Recovery Delay: 30 seconds
Fonksyon Reyajisteman Otomatik:
Nan ka ta gen yon twòp volimtage, undervoltage, 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, undervoltage, 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.
