Dimensioni del prodotto

Descrizione dell'immagine: This image displays the physical dimensions of the DEWIN Automatic Reclosing RCCB, showing measurements for height (82mm), width (49mm), and depth (54mm). It also includes a basic electrical circuit diagram illustrating the connections for the device.

5. Installazione e cablaggio

Proper installation is crucial for the safe and correct operation of the DEWIN RCCB. Refer to the wiring diagram below and ensure all connections are secure and comply with local electrical standards.

Schema elettrico

Descrizione dell'immagine: This diagram illustrates the electrical connections for the DEWIN Automatic Reclosing RCCB. It shows the incoming Line (L) and Neutral (N) connections, the output to various loads, and the auxiliary control connections for external opening and closing buttons. Note that for automatic reclosing, an external button is not required, but for manual control, a normally open self-reset button is used.

Fasi di cablaggio:

1. Mount the RCCB securely on a 35mm DIN rail within your electrical panel.
2. Connect the incoming Line (L) and Neutral (N) wires to the designated input terminals of the RCCB.
3. Connect the load wires to the output terminals of the RCCB.
4. For auxiliary control, connect external opening and closing buttons to the respective terminals (OPEN, CLOSE, COM). Ensure that for manual control, a normally open self-reset button is used.
5. Verify all connections are tight and correct before restoring power.

6. Istruzioni per l'uso

The DEWIN RCCB offers both automatic and manual operating modes, indicated by the 'AUTO' and 'MANU' selector switch.

Operating Modes and LED Display

Descrizione dell'immagine: This diagram details the automatic and manual switching modes of the DEWIN RCCB, along with the corresponding LED digital display indicators. It explains that in AUTO mode, red flashing indicates opening and green flashing indicates closing, while in MANU mode, a yellow light is always on for manual operation. The display also shows trip count and reclosing recovery time.

• Modalità automatica: In this mode, the circuit breaker will automatically attempt to restore power after a fault. The LED display will show:
  • Red flashing: Indicates the circuit is open (tripped).
  • Green flashing: Indicates the circuit is closed (reclosed).
• Modalità MANU: In this mode, if a fault occurs, the circuit breaker must be manually reset. The LED display will show:
  • Yellow light always on: Indicates manual opening and closing operation.
• Visualizzazione del codice non funzionante: The digital display shows the number of times the circuit has tripped and reclosed, along with the countdown time for reclosing recovery.

Self-Locking Mode

Descrizione dell'immagine: This image illustrates the self-locking mechanism of the DEWIN RCCB. It shows the progressive reclosing delays after a circuit fault: 9 seconds for the first reclosure, 59 seconds for the second, and 299 seconds for the third. After the fourth fault, the device enters a self-locking mode, requiring manual intervention. The image also includes a table defining different waveform types (AC, A) and their action ranges.

To prevent continuous reclosing into a persistent fault, the device implements a self-locking mechanism:

1. Primo errore: The circuit automatically recloses after 9 seconds.
2. Secondo errore: The circuit automatically recloses after 59 seconds.
3. Terzo errore: The circuit automatically recloses after 299 seconds.
4. Quarto errore: The recloser enters a self-locking mode. Manual inspection of the circuit and a manual reset operation are required before the device can be reclosed.

Nota: When the 'LOCK' mechanism is engaged (pulled up), the circuit breaker cannot be closed. This feature is designed to protect electrical safety and prevent accidental contact during inspection or maintenance.

7. Manutenzione

Regular maintenance ensures the longevity and reliability of your DEWIN RCCB.

• Test mensile: Press the 'Test Monthly' button on the device to verify its tripping function. The device should trip, and then reclose according to its programmed reclosing sequence (if in AUTO mode).
• Pulizia: Mantenere il dispositivo pulito e privo di polvere e detriti. Utilizzare un panno asciutto e morbido per la pulizia. Non utilizzare liquidi o detergenti abrasivi.
• Ispezione: Controllare periodicamente i collegamenti dei cavi per verificarne la tenuta e l'eventuale presenza di segni di usura o danni.

8. Risoluzione Dei Problemi

If you encounter issues with your DEWIN RCCB, refer to the following common problems and solutions:

• Device is Locked After Installation: If the device does not operate after initial power-up, it might be in a factory-locked state. Manually pull up the 'LOCK' mechanism to release it.
• LED Display Not Showing Voltage: This is normal operation. The LED display on this model is designed to indicate operational status and trip count, not voltage parametri.
• Device Enters Self-Locking Mode Frequently: Frequent tripping and entry into self-locking mode (after 4 consecutive faults) indicates a persistent electrical fault in the circuit. Disconnect power, thoroughly inspect the connected load and wiring for shorts, overloads, or ground faults, and rectify the issue before manually resetting the RCCB.
• Device Does Not Reclose in AUTO Mode: Ensure the selector switch is correctly set to 'AUTO'. If the device has entered self-locking mode due to multiple faults, it will require manual reset after fault clearance.
• Device Does Not Respond to Manual Operation: If in MANU mode, ensure the 'LOCK' mechanism is not pulled up. If it is, push it down to allow manual operation.

If the problem persists after attempting these troubleshooting steps, contact a qualified electrician or DEWIN customer support for assistance.
