5. Einrichtung und Installation
Eine fachgerechte Installation ist für die Leistungsfähigkeit und Sicherheit des Wechselrichters von entscheidender Bedeutung.
- Montage: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- DC-Eingangsanschluss:
- 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.
- Verwenden Sie Kabel mit dem passenden Querschnitt, um die Lautstärke zu minimieren.tage drop and ensure safe operation. Refer to electrical guidelines for cable sizing based on current and distance.
- Stellen Sie sicher, dass alle Verbindungen fest und sicher sind.
- Erdung: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- AC-Ausgangsanschluss:
- 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.
- Fernbedienung (optional): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Wichtig: Always ensure the inverter is OFF before making any connections.
6. Bedienung
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Einschalten: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Statusanzeigen: 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.
- Anschließen von Lasten: Plug your AC appliances into the GFCI outlets. Ensure the total wattagDie Gesamtleistung der angeschlossenen Geräte überschreitet nicht 3500 W.
- GFCI-Test: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Energiesparmodus: 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.
- Ausschalten: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
7. Wartung
Regelmäßige Wartung gewährleistet die Langlebigkeit und den zuverlässigen Betrieb Ihres Wechselrichters.
- Reinigung: Halten Sie den Wechselrichter sauber und frei von Staub und Schmutz. Wischen Sie die Außenseite mit einem trockenen Tuch ab. Verwenden Sie keine flüssigen Reinigungsmittel.
- Belüftung: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
