5. Impostazione

5.1 Wiring Display

Follow the wiring diagram carefully for correct installation. Ensure all connections are secure and properly insulated. The current transformer must be connected as shown.

Figure 5.1: Wiring connections for the 3-phase smart energy meter and current transformer.

• Collegamento del trasformatore di corrente: Press the yellow button to insert the connector, then connect it to the transformer.
• Importante: One neutral wire and three live wires must pass through the current transformer at the same time for accurate leakage detection. If the transformer is not connected, the leakage value cannot be detected.

5.2 Connessione Wi-Fi

The device connects to WiFi for smart control via the Tuya Smart APP. The WiFi indicator status provides feedback:

• Lampeggiamento veloce: Indica che il dispositivo sta cercando un segnale WiFi.
• Lampeggiamento lento: Indicates the device is offline.

If the device does not connect automatically, you can manually connect to WiFi by pressing and holding the third key (usually marked with a WiFi symbol or 'OK') for 3 seconds on the screen showing voltage. This will activate the hotspot for the app to connect.

6. Istruzioni per l'uso

6.1 Modalità di visualizzazione

The LCD screen cycles through various display modes, showing different electrical parameters. You can typically navigate these displays using the device's buttons or through the Tuya Smart APP.

6.2 Alarm Settings and Protection

The device supports various protection functions. You can set thresholds for overvoltage, sottovoltage, overcurrent, and leakage protection via the Tuya Smart APP. Once a threshold is exceeded, the alarm function automatically triggers, and the protection trip switch can be turned on or off as configured.

6.3 Timing Schedule

Utilize the timing schedule feature through the Tuya Smart APP to automate the control of your electrical circuits. This allows for efficient energy management and can help reduce electricity consumption.
