4. Setup and Installation
The Eltako WSZ15DE-32A is designed for DIN rail mounting. Follow these steps for proper installation:
- Mounting: Securely attach the meter to a standard DIN rail in an electrical distribution box. The meter features clips on the back for easy installation.
- Wiring: Refer to the wiring diagram on the device label for correct connections.
- Connect the incoming phase (L) to the 'IN' terminal.
- Connect the outgoing phase (L) to the 'OUT' terminal.
- Connect the incoming neutral (N) to the 'N' terminal.
- Connect the outgoing neutral (N) to the 'N' terminal.
- For S0 pulse output, connect S0+ and S0- terminals to a compatible pulse counter or data logger.
- Verification: After wiring, double-check all connections for tightness and correctness before restoring power.

The diagram clearly illustrates connections for Phase (IN/OUT), Neutral (N), and S0 output (S0+/S0-), along with the energy reading on the LCD.
5. Operating Instructions
Once installed and powered, the Eltako WSZ15DE-32A meter will automatically begin measuring and displaying energy consumption.
Reading the Display:
The LCD display shows the total accumulated energy consumption in kilowatt-hours (kWh). The reading is typically displayed with two decimal places.
S0 Pulse Output:
The S0 output provides electrical pulses proportional to the energy consumed. This can be connected to external systems for remote monitoring or data logging. The pulse rate is 1000 Imp/kWh for the LCD and 2000 Imp/kWh for the S0 output.
6. Maintenance
The Eltako WSZ15DE-32A is a low-maintenance device. Follow these guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the meter. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the wiring connections for any signs of loosening or damage.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
7. Troubleshooting
If you encounter issues with your Eltako WSZ15DE-32A meter, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; incorrect wiring. | Check power supply to the circuit. Verify wiring connections according to the diagram. |
| Meter not counting energy | Incorrect wiring; no load connected. | Ensure phase and neutral connections are correct and a load is drawing current. |
| S0 output not working | Incorrect S0 wiring; incompatible external device. | Verify S0+ and S0- connections. Consult the manual for the external pulse counter. |
If the problem persists, contact qualified technical support.
