4. Configurazione e installazione
The KWS-303 meter is designed for easy installation on a standard 35mm DIN rail. Follow these steps carefully:
- Disconnessione dell'alimentazione: Before starting, ensure that the main power supply to the circuit where the meter will be installed is completely disconnected. Use appropriate lockout/tagle nostre procedure.
- Montaggio: Fissare il misuratore su una guida DIN standard da 35 mm nel quadro elettrico. Assicurarsi che sia fissato saldamente.
- Cablaggio: Connect the input and output wires according to the diagram below.
- Collegare il Zero Line In (N) to the neutral wire from the power source.
- Collegare il Fire Line In (L) to the live wire from the power source.
- Collegare il Zero Line Out (N) to the neutral wire of the load.
- Collegare il Fire Line Out (L) to the live wire of the load.
- Ensure the temperature sensing interface (NTC) is connected if temperature monitoring is desired.
- Verifica connessioni: Double-check all wiring connections for correctness and tightness to prevent loose contacts and potential hazards.
- Ripristina alimentazione: Once installation is complete and verified, restore power to the circuit. The meter display should illuminate.

5. Istruzioni per l'uso
The KWS-303 meter provides real-time monitoring and protection. Here’s how to operate its main functions:
5.1 Display e navigazione
Upon power-up, the HD LCD screen will display all 8 measurement parameters simultaneously. The display is designed for a 178-degree viewing angle, ensuring readability from various positions.
5.2 One-Touch Zero Reset Function
The meter features a convenient one-touch zero reset function for specific parameters:
- Per reimpostare il Electricity (kWh) reading: Press and hold the designated reset button (refer to the device's physical buttons, typically marked with a reset icon or '–' button for specific models) until the kWh value resets to zero.
- Per reimpostare il Tempo measurement: Similarly, press and hold the appropriate button to reset the accumulated time.
This function is useful for monitoring energy consumption or operation time over specific periods.
5.3 Conservazione dei dati
The KWS-303 meter automatically saves the last recorded test data. In the event of a power outage, the data is retained. When power is restored, the meter will continue to accumulate data from the last saved point, preventing data loss.

5.4 Funzionalità di protezione
The meter incorporates several protection mechanisms to safeguard your electrical system and connected devices:
- Sovravoltage Protezione: Disconnette automaticamente il circuito se il voltage exceeds a safe threshold.
- Sottovoltage Protezione: Disconnects the circuit if the voltage scende al di sotto di un minimo di sicurezza.
- Protezione da sovracorrente: Trips the circuit if the current draw exceeds the rated ampetà (40A).
- Protezione da sovratemperatura: Shuts down the circuit if the internal temperature or sensed external temperature (if NTC is connected) becomes dangerously high.
These protection features help prevent damage to appliances and ensure electrical safety. The meter will typically display an error code or indicator when a protection event occurs.

7. Risoluzione Dei Problemi
If you encounter issues with your KWS-303 meter, refer to the following common troubleshooting steps:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il display è vuoto | Nessuna alimentazione; Cablaggio allentato; Malfunzionamento del dispositivo. | Check main power supply. Verify all wiring connections are secure. If power is present and wiring is correct, contact support. |
| Letture errate | Improper wiring; Sensor issue; Device malfunction. | Review wiring diagram (Image 4.1) and ensure correct connections. Check if the NTC temperature sensor is properly connected. Contact support if issues persist. |
| Protection trip (e.g., power cut off) | Sovravoltage, sottovoltage, overcurrent, or overtemperature condition detected. | Identify and resolve the underlying electrical issue (e.g., reduce load, check power supply stability, ensure proper ventilation). The meter will typically reset automatically once the condition is resolved, or may require a manual power cycle. |
| Reset function not working | Button not pressed correctly; Device malfunction. | Ensure the reset button is pressed and held for the required duration. If still unresponsive, contact support. |
