5. Installation Instructions
The BEMKO A30-BM030-L electric meter is designed for installation on a standard 35mm DIN rail. Ensure all safety precautions are followed before beginning installation.
5.1 Mounting
- Disconnect Power: Ensure the main power supply to the installation area is completely disconnected and locked out.
- Select Location: Choose a dry, well-ventilated location within the specified operating temperature range (-10 °C to +45 °C) and IP20 protection.
- Mount on DIN Rail: Clip the meter onto a standard 35mm DIN rail. Ensure it is securely fastened.
5.2 Wiring
Refer to the wiring diagram below for correct connection of the three-phase and neutral lines. Incorrect wiring can damage the meter or pose a safety hazard.
Figure 5.1: Wiring diagram for the BEMKO A30-BM030-L 3-Phase Electric Meter. Terminals 1, 3, 5, 7 are for input (IN) L1, L2, L3, N respectively. Terminals 2, 4, 6, 8 are for output (OUT) L1, L2, L3, N respectively.
Figure 5.2: Close-up view of the terminal blocks on the BEMKO A30-BM030-L electric meter, showing connections for phases and neutral.
- Connect the incoming Phase 1 (L1) to terminal 1.
- Connect the outgoing Phase 1 (L1) to terminal 2.
- Connect the incoming Phase 2 (L2) to terminal 3.
- Connect the outgoing Phase 2 (L2) to terminal 4.
- Connect the incoming Phase 3 (L3) to terminal 5.
- Connect the outgoing Phase 3 (L3) to terminal 6.
- Connect the incoming Neutral (N) to terminal 7.
- Connect the outgoing Neutral (N) to terminal 8.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
- After wiring, double-check all connections against the diagram before restoring power.
6. Operating Instructions
Once properly installed and powered, the BEMKO A30-BM030-L electric meter will automatically begin measuring energy consumption.
Figure 6.1: Close-up of the BEMKO A30-BM030-L LCD display, showing the 6+2 digit energy reading in kWh.
6.1 Reading the Display
- The LCD displays the total active energy consumed in kilowatt-hours (kWh).
- The display format is 6+2 digits, meaning six digits for whole kWh and two digits for decimal kWh (e.g., 000000.01 kWh).
6.2 Pulse Output
- The meter features an LED indicator that flashes at a rate of 1000 pulses per kWh (1000 imp/kWh). This provides a visual indication of energy consumption.
- The pulse output is inactive, meaning it is for visual indication only and not for external connection to other systems.
7. Maintenance
The BEMKO A30-BM030-L electric meter is designed for maintenance-free operation. No internal user-serviceable parts are present.
- Cleaning: If necessary, gently wipe the exterior of the meter with a soft, dry cloth. Do not use abrasive cleaners, solvents, or liquids directly on the device.
- Inspection: Periodically inspect the wiring connections to ensure they remain secure.
- Environmental: Ensure the operating environment remains within the specified temperature and humidity limits.
8. Troubleshooting
If you encounter issues with your BEMKO A30-BM030-L electric meter, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or off. | No power supply to the meter. | Check the main power supply and all wiring connections. Ensure power is restored. |
| Meter not registering consumption. | Incorrect wiring or no load connected. | Verify wiring against the diagram (Figure 5.1). Ensure there is an active electrical load connected downstream of the meter. |
| Pulse LED not flashing. | No energy consumption or meter malfunction. | Confirm that there is an active load drawing power. If the display shows consumption but the LED does not flash, contact support. |
| Meter appears damaged. | Physical damage. | Do not operate. Disconnect power immediately and contact the supplier for replacement or repair. |
If the problem persists after following these steps, please contact your supplier or a qualified electrician.
