4.2 Wiring Connections
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.
Figure 4.2: Side 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. Operating Instructions
Once installed and powered, the meter will automatically begin measuring energy consumption.
5.1 Reading the Display
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 Pulse Output
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. Maintenance
The BEMKO A31-BL01A-MID electricity meter is designed for long-term, maintenance-free operation under normal conditions.
- Cleaning: If necessary, gently wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: 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.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges and free from excessive dust or moisture.
7. Troubleshooting
If you encounter issues with your electricity meter, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter display is blank | No power supply to the meter. | Check the main circuit breaker and wiring connections. Ensure power is restored. |
| Meter not accumulating kWh | Incorrect wiring or no load connected. | 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. |
| Unusual noises or smells | Internal fault or overheating. | 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.
