2. Informazioni sulla sicurezza
Osservare sempre le seguenti precauzioni di sicurezza per ridurre il rischio di scosse elettriche, incendi o lesioni.
- Sicurezza elettrica: Non aprire l'inverter casing. All'interno non sono presenti parti riparabili dall'utente. Per qualsiasi intervento di manutenzione, rivolgersi a personale qualificato.
- Ventilazione: Assicurare un'adeguata ventilazione attorno all'inverter. Non ostruire le aperture di ventilazione.
- Ambiente: Install the inverter in a dry, cool, and well-ventilated area, away from flammable materials, corrosive chemicals, and direct sunlight.
- Collegamento della batteria: Connect the inverter directly to a 12V DC battery bank using appropriate gauge cables. Ensure correct polarity (+ to + and - to -). Reverse polarity will damage the inverter.
- Messa a terra: Collegare correttamente a terra il telaio dell'inverter a una messa a terra affidabile.
- Capacità di carico: Do not exceed the inverter's rated output power (3500W continuous). Overloading can cause damage and fire hazards.
- Protezione GFCI: The integrated GFCI outlets provide protection against ground faults. Test the GFCI regularly as per local electrical codes.

5. Configurazione e installazione
Un'installazione corretta è fondamentale per le prestazioni e la sicurezza dell'inverter.
- Montaggio: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- Collegamento ingresso CC:
- Connect the positive (+) terminal of the 12V battery bank to the positive (+) DC input terminal on the inverter.
- Connect the negative (-) terminal of the 12V battery bank to the negative (-) DC input terminal on the inverter.
- Use appropriately sized cables to minimize voltage drop and ensure safe operation. Refer to electrical guidelines for cable sizing based on current and distance.
- Assicurarsi che tutti i collegamenti siano ben saldi e sicuri.
- Messa a terra: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- Collegamento di uscita CA:
- Plug your AC appliances directly into the GFCI outlets on the inverter.
- For hardwired applications, consult a qualified electrician to connect to the AC output terminals.
- AC Input Connection (for ATS function): If using the automatic transfer switch, connect a reliable AC power source (e.g., shore power, generator) to the AC input terminals.
- Telecomando (opzionale): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Importante: Always ensure the inverter is OFF before making any connections.
6. Funzionamento
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Accensione: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Indicatori di stato: Observe the LED indicators on the inverter (if present) for status such as power, fault, or overload. Refer to the full manual for detailed indicator meanings.
- Collegamento dei carichi: Plug your AC appliances into the GFCI outlets. Ensure the total wattagla potenza degli apparecchi collegati non supera i 3500W.
- Prova GFCI: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Modalità di risparmio energetico: If configured, the inverter may enter a power-saving mode when no load or a very light load is detected, reducing quiescent current draw.
- Automatic Transfer Switch (ATS): If an AC input source is connected, the inverter will automatically switch to that source when available, prioritizing it over battery power. When the AC input is lost, it will switch back to inverter (battery) power.
- Spegni: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
7. Manutenzione
Una manutenzione regolare garantisce la longevità e il funzionamento affidabile del vostro inverter.
- Pulizia: Mantenere l'inverter pulito e privo di polvere e detriti. Utilizzare un panno asciutto per pulire l'esterno. Non utilizzare detergenti liquidi.
- Ventilazione: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
- Connessioni: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
- Stato della batteria: Monitor the health of your battery bank. A weak battery can affect inverter performance.
- Prova GFCI: Test the GFCI outlets monthly to ensure proper function.
