4.2配線接続
Refer to the wiring diagram typically found on the meter's casing or in the manufacturer's detailed technical documentation. Ensure correct connection of live (L) and neutral (N) wires for both input and output. The meter supports a nominal current of 100A.
図4.2：側面 view showing the terminal block for electrical connections (L and N terminals).
- Connect the incoming live wire to the designated input terminal (L-in).
- Connect the incoming neutral wire to the designated input terminal (N-in).
- Connect the outgoing live wire to the designated output terminal (L-out).
- Connect the outgoing neutral wire to the designated output terminal (N-out).
- Tighten all terminal screws securely to prevent loose connections and overheating.
After all connections are made and verified, restore power to the circuit.
5. 操作手順
Once installed and powered, the meter will automatically begin measuring energy consumption.
5.1 ディスプレイの読み方
The digital display shows the total accumulated energy consumption in kilowatt-hours (kWh). The display is continuous and does not require any button presses for basic reading.

5.2 パルス出力
The meter features a pulse output, indicated by an LED or similar mechanism, typically labeled "2000 imp/kWh". This means the meter generates 2000 pulses for every kilowatt-hour of energy consumed. This output can be used for remote monitoring or integration with other systems.
6. メンテナンス
The BEMKO A31-BL01A-MID electricity meter is designed for long-term, maintenance-free operation under normal conditions.
- クリーニング： If necessary, gently wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- 検査： Periodically inspect the meter and its connections for any signs of damage, loose wiring, or discoloration. Address any issues promptly by disconnecting power and consulting a qualified electrician.
- 環境： Ensure the operating environment remains within the specified temperature and humidity ranges and free from excessive dust or moisture.
7。 トラブルシューティング
If you encounter issues with your electricity meter, consider the following common problems and solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| メーターの表示が空白です | メーターに電源が供給されていません。 | Check the main circuit breaker and wiring connections. Ensure power is restored. |
| Meter not accumulating kWh | 配線が間違っているか、負荷が接続されていません。 | Verify wiring connections according to the diagram. Ensure there is an active electrical load. |
| Pulse indicator (LED) not flashing | No power consumption or faulty meter. | Confirm that electrical devices are drawing power. If consumption is active and the LED is off, contact support. |
| 異常な音や臭い | 内部障害または過熱。 | Immediately disconnect power. Do not attempt to repair. Contact a qualified electrician or manufacturer support. |
For issues not listed here or if troubleshooting steps do not resolve the problem, contact qualified technical support.
