2. Informazioni sulla sicurezza

ATTENZIONE: Pericolo di scossa elettrica. L'installazione e la manutenzione devono essere eseguite solo da personale qualificato.

• Scollegare sempre l'alimentazione prima di installare o effettuare la manutenzione del dispositivo.
• Assicurarsi che tutti i collegamenti elettrici siano sicuri e conformi alle normative elettriche locali.
• Non utilizzare il dispositivo in ambienti bagnati o damp condizioni.
• Verificare il volumetage and current ratings of your system match the device specifications.
• Never attempt to open or repair the device yourself. Refer to qualified service personnel.

3. Caratteristiche principali

The TOMZN TOVPD3-63VA offers robust protection and monitoring capabilities:

• Instant Fault Response: Detects and reacts to electrical abnormalities within milliseconds to prevent equipment damage.
• Sistema multiprotezione: Comprehensive coverage against overcurrent, under-voltage, phase loss, and short circuits.
• Durata di livello industriale: Heavy-duty construction with flame-retardant materials for demanding environments.
• Compatibilità universale: Works with AC/DC systems, motors, transformers, and power distribution panels.
• Clear Visual Indicators: LED status lights and fault alarms for quick system diagnostics.
• Sovra-volume regolabiletage, sotto-volumetage, and over-current protection thresholds.
• Asymmetry and phase sequence protection.
• Adjustable active time and reconnect time.
• Volume manualetage and current calibration capability.

4. Varianti del prodotto

The TOVPD3 series is available in several configurations to suit different electrical systems. The primary differences lie in the current rating and the presence of a neutral (N) connection, which affects the voltage display and wiring:

• 63A With N (3X120V/3X220V/3X230V): Designed for 3-phase systems with a neutral line. Each phase voltage (L1, L2, L3) is displayed relative to the neutral. For example, in a 3*220V+N system, each phase will display 220V.
• 63A without N (380V): Designed for 3-phase systems without a neutral line. The device displays the line-to-line voltage for each phase (e.g., L1-L2, L2-L3, L3-L1), typically showing 380V across all phases.
• 100A With N (3X220V): Similar to the 63A With N variant but with a higher current capacity.
• 100A without N (380V): Similar to the 63A without N variant but with a higher current capacity.

Ensure you select the correct variant for your specific electrical installation.

5. Componenti e display

The device features a clear digital display and intuitive control buttons for monitoring and configuration.

6. Installazione

6.1 Montaggio

The TOMZN TOVPD3-63VA is designed for Din Rail mounting. Ensure the Din Rail is securely installed in an appropriate electrical enclosure, away from moisture and excessive heat.

6.2 Cablaggio

IMPORTANT: Disconnect all power before proceeding with wiring.

1. Identify the input (IN) and output (OUT) terminals on the device. The terminals are typically labeled L1, L2, L3, and N (if applicable).
2. Connect the incoming three-phase power supply to the 'IN' terminals (L1, L2, L3). If your model includes a neutral connection, connect the neutral line to the 'N' terminal.
3. Connect the load (equipment to be protected) to the 'OUT' terminals (L1, L2, L3). If your model includes a neutral connection, connect the load's neutral line to the 'N' output terminal.
4. Ensure all connections are tight and secure to prevent loose contacts, which can cause overheating or malfunction.
5. Double-check all wiring against your system's electrical diagram and local codes before restoring power.
