Негизги өзгөчөлүктөрү:
- 20 Ampere (A) rated current.
- 30 миллиampere (mA) residual current sensitivity.
- Designed for circuit protection against earth leakage.
- Robust construction for demanding environments.
4. Орнотуу жана орнотуу
Before beginning installation, ensure the main power supply to the circuit is completely disconnected and verified as de-energized.
Орнотуу кадамдары:
- Монтаждоо: Select a suitable, dry, and protected location for mounting the RCD breaker. Ensure adequate ventilation and accessibility for future maintenance. Secure the breaker using appropriate fasteners through the designated mounting holes.
- Зымдар:
- Connect the incoming live (phase) wire to the 'L' terminal and the incoming neutral wire to the 'N' terminal on the input side of the RCD.
- Connect the outgoing live (phase) wire to the 'L' terminal and the outgoing neutral wire to the 'N' terminal on the output side of the RCD, leading to the protected circuit.
- Ensure all connections are tight and secure to prevent loose contacts and overheating. Use appropriate wire gauges for the 20A rating.
- Текшерүү: Double-check all wiring connections against the circuit diagram. Ensure no bare wires are exposed and that the RCD is correctly oriented for current flow.
- Электр энергиясын калыбына келтирүү: Орнотуу аяктагандан жана текшерилгенден кийин, чынжырга электр кубатын кайтарыңыз.
5. Иштөө нускамалары
The BEP Marinco RCD20A30MA operates automatically to detect and interrupt earth leakage currents. It does not require manual operation for its primary protective function.
Кадимки операция:
- When power is supplied and no earth leakage is detected, the RCD will remain in the 'ON' (closed circuit) position, allowing current to flow to the protected circuit.
- In the event of an earth leakage fault exceeding 30mA, the RCD will automatically trip to the 'OFF' (open circuit) position, disconnecting the power supply to prevent electric shock.
Resetting the RCD:
If the RCD trips, it indicates an earth leakage fault. Before resetting, identify and rectify the cause of the fault. Once the fault is cleared:
- Ensure the power to the affected circuit is off.
- Push the RCD lever fully to the 'OFF' position.
- Then, push the lever to the 'ON' position to reset the RCD.
- If the RCD trips again immediately, the fault has not been cleared or there is a persistent issue. Do not attempt to reset repeatedly without addressing the underlying problem.
6. Техникалык тейлөө
Regular testing of the RCD is essential to ensure its proper functioning and continued protection.
Monthly Test Procedure:
- Ensure power is supplied to the RCD and the protected circuit is operational.
- Locate the 'TEST' button on the front of the RCD.
- Press the 'TEST' button. The RCD should immediately trip to the 'OFF' position. This confirms the internal tripping mechanism is working.
- Reset the RCD by pushing the lever fully to 'OFF' and then to 'ON'.
- If the RCD does not trip when the 'TEST' button is pressed, or if it fails to reset, the device may be faulty and should be replaced immediately by a qualified electrician.
Beyond this monthly test, no other user-serviceable parts or routine maintenance are required. Keep the device clean and free from dust and debris.
7. Кыйынчылыктарды
This section outlines common issues and their potential solutions. For complex problems, consult a qualified electrician.
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| RCD trips frequently or immediately after resetting. | Persistent earth leakage fault in the protected circuit (e.g., faulty appliance, damaged wiring). Схемадагы ашыкча жүк. Faulty RCD. | Disconnect all appliances from the circuit and try resetting. If it holds, reconnect appliances one by one to identify the faulty one. Inspect wiring for damage. If the problem persists with no load, the RCD may be faulty and requires replacement. |
| RCD does not trip when 'TEST' button is pressed. | RCD is faulty. No power to the RCD. | Verify power supply to the RCD. If power is present and it still doesn't trip, the RCD is faulty and must be replaced immediately. |
| RCD does not reset. | Persistent earth leakage fault. Internal mechanical fault in the RCD. | Ensure the fault in the circuit has been cleared. If the fault is cleared and it still won't reset, the RCD is likely faulty and needs replacement. |
