5.2.1. Connecting AC Input Cable
- Connect the AC Input cable to a socket near the Electrical Box to power on the Power Clamp nurutkeun diagram wiring fase pakait.
- Attach both ends of the Current Transformer Cables. Spin the waterproof latch clockwise until both ends are tightened and secured.
5.2.2. Connecting CT Clamps
Buka clamp and apply it to the electric meter cable. The arrow on the clamp should face the correct direction of the electricity current flow (P1→P2). If the arrow faces the reverse direction, the reading meter will display 0.
Catetan penting:
- The phase of the circuit measured by the CT needs to be consistent with the power supply phase of that CT. For example, if the CT of L1 measures the L1 circuit, the power supply for L1 must also be connected to the L1 phase. You cannot clamp the CT of L1 on the L2 phase if the power supply of L1 is still connected to the L1 phase.
- Pastikeun clamp of L1/L2/L3 corresponds to L1/L2/L3 of the circuit to be tested.
- Panah dina clamp should face the correct direction of the electricity current flows.

7. Parentah Operasi
Once installed and configured, the EARU PC321-TY energy meter allows you to monitor various electrical parameters through the Smart Life App.
7.1. Pangimeutan sacara real-time
Monitor Current, Active Power, Voltage, and Power Factor in real-time. Daily, weekly, and monthly consumption and production data can be viewed with charts in the Tuya App. This allows you to see how much electricity you are consuming, when, and how much excess energy you are producing back to the grid.
7.2. Bidirectional Measurement (WiFi Version Only)
The WiFi version supports bidirectional measurement, allowing you to track both energy consumption ("From Grid" energy) and energy production ("To Grid" energy), which is particularly useful for solar panel installations.
- Klip Clamp1 onto Grid: Measures "From Grid" or "To Grid" energy. If the measured current direction is P1→P2, energy is accumulated as "From Grid" energy. If P2→P1, energy is accumulated as "To Grid" energy.
- Klip Clamp2 onto Inverter: Measures how much energy is generated by the inverter. The clamp direction needs to point to the Inverter.
- Klip Clamp3 onto Load: Measures how much energy is consumed by the load. The clamp direction needs to point to the Load.
7.3. Kontrol sora
The device supports voice control through intelligent speakers like Amazon Alexa and Google Assistant, allowing for hands-free operation.

- Ulah nepi ka alat kakeunaan sinar panonpoé langsung, kalembaban anu luhur, atanapi suhu anu ekstrim.
- Regularly check wiring connections for tightness and integrity.
- If the device malfunctions, do not attempt to repair it yourself. Contact qualified personnel.
Ngareset Alat:
To restore the power clamp to default factory settings (energy data will not be cleared), press and hold the reset button for 5 seconds until the Red LED indicator flashes 3 times quickly. The device will then enter EZ mode for 3 minutes.
To clear energy data, reset the Power Clamps twice consecutively. The interval between two resets must be less than 10 seconds. After successful operation, the indicator light will flash alternately red and green 3 times.
9. Cara ngungkulan
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Alat teu hurung | No power to AC input cable or faulty connection. | Check AC input cable connection and power source. Ensure main power is on after installation. |
| LED indicator not flashing red during pairing | Device not in pairing mode or already paired. | Press and hold the reset button for 5 seconds to enter pairing mode. |
| Inaccurate readings or 0 display | Incorrect CT clamp direction or phase mismatch. | Ensure the arrow on the CT clamp points towards the load. Verify that the CT clamp for each phase (L1, L2, L3) is connected to its corresponding phase wire. |
| No data in Smart Life App | Device not connected to network or out of range. | Check WiFi (2.4GHz) or ZigBee gateway connection. Ensure device is within signal range. Re-pair if necessary. |
| ZigBee version not showing bidirectional measurement | ZigBee protocol limitation. | Bidirectional measurement is only supported by the WiFi version. This is expected behavior for ZigBee models. |
10. Tips pamaké
- Sarat Kawat Nétral: The meter requires a neutral wire for accurate voltage, current, and power measurements. Ensure your measured circuit includes a neutral wire.
- CT Clamp arah: Always double-check the direction of the arrow on the CT clamps. It must point towards the load for correct consumption readings. For solar generation, the arrow should point away from the load (towards the grid/inverter).
- Phase Correspondence: When using multiple CT clamps in a three-phase system, ensure that each clamp (L1, L2, L3) is correctly installed on its corresponding phase wire. Mismatched phases will lead to incorrect data.
- App Data Visualization: The Smart Life app provides bar graphs for kWh consumption per phase. While current measurements are available, trend lines for current might not be directly supported in the same graphical format as energy consumption.
- Alerts and Routines: The device can often be integrated with smart home platforms like Alexa for routines. Check the Smart Life app for options to set up alerts based on consumption or lack thereof, and to create routines with other smart devices.
- Kakuatan sinyal: For ZigBee versions, ensure the device is close enough to the ZigBee gateway for a stable connection. For WiFi, a strong 2.4GHz signal is crucial.
