4.インストールガイド
This section provides instructions for the safe and correct installation of the DZ47LE-32 RCCB. Ensure all safety precautions in Section 2 are followed.
4.1 取り付け
The DZ47LE-32 RCCB is designed for DIN rail mounting.
- Ensure the DIN rail is securely installed within the electrical panel or enclosure.
- Align the circuit breaker's mounting clips with the DIN rail.
- Press the circuit breaker firmly onto the DIN rail until it clicks into place. Verify it is securely fastened and does not wobble.

4.2配線
Refer to the wiring diagram on the device and ensure correct polarity and connections.
- 電源を切る: 作業を始める前に、回路への主電源が完全に切断されていることを確認してください。
- 端末を識別します: The device has input terminals at the top and output terminals at the bottom. The labels on the device indicate the Live (L) and Neutral (N) connections.
- 入力ワイヤを接続します。 Connect the incoming Live and Neutral wires to the corresponding top terminals. Ensure the wires are stripped to the correct length and inserted fully into the terminals.
- 出力線を接続します。 Connect the outgoing Live and Neutral wires to the corresponding bottom terminals. These wires will lead to the load circuit.
- ネジを締めます: Use a suitable screwdriver to securely tighten all terminal screws. Do not overtighten, but ensure connections are firm to prevent arcing or overheating.
- 接続を確認します。 電源を復旧する前に、すべての配線の正確性と安全性を再確認してください。

5. 操作手順
Once installed and wired correctly, the DZ47LE-32 RCCB is ready for operation.
5.1オン/オフの切り替え
- スイッチをオンにするには: Push the main blue lever upwards to the 'ON' position. The green indicator will be visible.
- スイッチを切る: Push the main blue lever downwards to the 'OFF' position. The red indicator will be visible.
- トリップ表示: If the device trips due to a fault (leakage, overload, or short-circuit), the lever will move to an intermediate position. To reset, first push the lever fully down to 'OFF', then push it up to 'ON'.
5.2 テスト機能
The RCCB includes a test button to verify its functionality. This test should be performed monthly.
- Ensure the circuit breaker is in the 'ON' position and power is supplied to the circuit.
- Press the orange 'T' (Test) button located on the front of the device.
- The circuit breaker should immediately trip, moving the lever to the 'OFF' or intermediate position, and cutting power to the protected circuit.
- If the device does not trip, it may be faulty and should be inspected or replaced by a qualified electrician.
- To restore power, reset the circuit breaker by pushing the lever fully down to 'OFF', then up to 'ON'.

6. メンテナンス
The SEAFRONT DZ47LE-32 RCCB requires minimal maintenance, primarily consisting of regular functional checks.
- 月次テスト: As described in Section 5.2, press the 'T' (Test) button monthly to ensure the residual current protection mechanism is functioning correctly.
- 目視検査: Periodically inspect the device for any signs of physical damage, discoloration, or loose connections. Any abnormalities should be addressed by a qualified electrician.
- クリーニング: If necessary, gently wipe the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
7。 トラブルシューティング
If the DZ47LE-32 RCCB trips unexpectedly or fails to operate, consider the following common issues:
- 頻繁につまずく:
- Leakage Fault: A leakage current may be present in the circuit or connected appliances. Disconnect appliances one by one to identify the faulty device.
- オーバーロード: The total current drawn by connected devices exceeds the RCCB's rated current (32A). Reduce the load or redistribute it across different circuits.
- 短絡: A direct short-circuit between live and neutral wires. This requires immediate investigation by a qualified electrician.
- RCCB Does Not Trip During Test: If pressing the 'T' button does not trip the device, the RCCB may be faulty. It should be replaced immediately by a qualified electrician.
- Power Does Not Restore After Tripping: Ensure the lever is pushed fully down to 'OFF' before attempting to push it up to 'ON'. If it still does not reset, there might be a persistent fault in the circuit or the device itself.
- 緩い接続: Check all wiring connections for tightness. Loose connections can cause intermittent tripping or overheating.
For persistent issues or if you are unsure about troubleshooting steps, always consult a qualified electrician.
