5.2 Wiring
Refer to the wiring diagram printed on the meter and Figure 1 for terminal identification. Ensure correct polarity and secure connections.
- Phase (L) Input: Connect the incoming live wire to the "L IN" terminal.
- Phase (L) Output: Connect the outgoing live wire to the "L OUT" terminal.
- Neutral (N) Input: Connect the incoming neutral wire to the "N IN" terminal.
- Neutral (N) Output: Connect the outgoing neutral wire to the "N OUT" terminal.
After wiring, double-check all connections for tightness and correctness before restoring power.
6. Operating Instructions
Once installed and powered, the meter will automatically begin measuring energy consumption.
6.1 Display and Buttons
The meter features a digital display and two control buttons:
- Display: Shows energy consumption in kWh, and potentially instantaneous power (W) or apparent power (kW) depending on the mode.
- MODE Button: Used to cycle through different display parameters (e.g., kWh, W, kW).
- SELECT Button: Used for selecting or confirming options, or resetting certain values if applicable (refer to specific model features).
6.2 Reading Energy Consumption
The primary reading is typically in kWh (kilowatt-hours), which represents the total energy consumed over time. Press the MODE button to view different parameters if available.
7. Maintenance
The Eltako WZR12-32A energy meter requires minimal maintenance.
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- There are no user-serviceable parts inside the meter. Do not attempt to open or repair the device.
8. Troubleshooting
If you encounter issues with your energy meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display / Meter not turning on | No power supply to the meter; incorrect wiring. | Check main power supply. Verify all wiring connections are correct and secure according to the diagram. |
| Incorrect readings | Incorrect wiring; faulty device. | Ensure wiring is correct (Phase IN/OUT, Neutral). If problem persists, contact customer support. |
| Buttons unresponsive | Temporary software glitch; faulty buttons. | Try briefly disconnecting and reconnecting power (if safe to do so). If problem persists, contact customer support. |
