2. Sikkerhedsoplysninger
Overhold altid følgende sikkerhedsforanstaltninger for at mindske risikoen for elektrisk stød, brand eller personskade.
- Elektrisk sikkerhed: Åbn ikke inverteren casing. Der er ingen dele indeni, som kan serviceres af brugeren. Overlad al service til kvalificeret personale.
- Ventilation: Sørg for tilstrækkelig ventilation omkring inverteren. Ventilationsåbningerne må ikke blokeres.
- Miljø: Install the inverter in a dry, cool, and well-ventilated area, away from flammable materials, corrosive chemicals, and direct sunlight.
- Batteriforbindelse: 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.
- Jording: Forbind inverterens chassis korrekt til en pålidelig jordforbindelse.
- Belastningskapacitet: Do not exceed the inverter's rated output power (3500W continuous). Overloading can cause damage and fire hazards.
- GFCI beskyttelse: The integrated GFCI outlets provide protection against ground faults. Test the GFCI regularly as per local electrical codes.

5. Opsætning og installation
Korrekt installation er afgørende for inverterens ydeevne og sikkerhed.
- Montering: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- DC-indgangsforbindelse:
- 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.
- Brug kabler i den rigtige størrelse for at minimere lydstyrkentage drop and ensure safe operation. Refer to electrical guidelines for cable sizing based on current and distance.
- Sørg for, at alle forbindelser er tætte og sikre.
- Jording: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- AC-udgangstilslutning:
- 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.
- Fjernbetjening (valgfrit): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Vigtig: Always ensure the inverter is OFF before making any connections.
6. Betjening
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Tænd: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Statusindikatorer: 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.
- Tilsluttede belastninger: Plug your AC appliances into the GFCI outlets. Ensure the total wattage of connected appliances does not exceed 3500W.
- GFCI test: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Strømbesparelsestilstand: If configured, the inverter may enter a power-saving mode when no load or a very light load is detected, reducing quiescent current draw.
- Automatisk omskifter (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.
- Sluk: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
7. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer din inverters lange levetid og pålidelige drift.
- Rensning: Hold inverteren ren og fri for støv og snavs. Brug en tør klud til at tørre ydersiden af. Brug ikke flydende rengøringsmidler.
- Ventilation: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
- Forbindelser: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
- Batteriets sundhed: Monitor the health of your battery bank. A weak battery can affect inverter performance.
- GFCI test: Test the GFCI outlets monthly to ensure proper function.
