2. Varnostne informacije
Vedno upoštevajte naslednje varnostne ukrepe, da zmanjšate tveganje električnega udara, požara ali poškodb.
- Električna varnost: Ne odpirajte pretvornika casing. V notranjosti ni delov, ki bi jih lahko uporabnik popravil. Vsa servisna dela prepustite usposobljenemu osebju.
- Prezračevanje: Zagotovite zadostno prezračevanje okoli razsmernika. Ne blokirajte prezračevalnih odprtin.
- Okolje: Install the inverter in a dry, cool, and well-ventilated area, away from flammable materials, corrosive chemicals, and direct sunlight.
- Priključek baterije: 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.
- Ozemljitev: Properly ground the inverter chassis to a reliable earth ground.
- Nosilnost: Do not exceed the inverter's rated output power (3500W continuous). Overloading can cause damage and fire hazards.
- Zaščita GFCI: The integrated GFCI outlets provide protection against ground faults. Test the GFCI regularly as per local electrical codes.

5. Nastavitev in namestitev
Pravilna namestitev je ključnega pomena za delovanje in varnost pretvornika.
- Montaža: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- DC vhodna povezava:
- 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.
- Prepričajte se, da so vse povezave tesne in varne.
- Ozemljitev: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- Priključek izhoda AC:
- 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.
- Daljinski upravljalnik (izbirno): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Pomembno: Always ensure the inverter is OFF before making any connections.
6. Delovanje
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Vklop: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Kazalniki stanja: 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.
- Priključne obremenitve: Plug your AC appliances into the GFCI outlets. Ensure the total wattage of connected appliances does not exceed 3500W.
- Test GFCI: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Način varčevanja z energijo: 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.
- Ugasniti: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
7. Vzdrževanje
Redno vzdrževanje zagotavlja dolgo življenjsko dobo in zanesljivo delovanje vašega inverterja.
- Čiščenje: Razsmernik naj bo čist in brez prahu ter umazanije. Zunanjost obrišite s suho krpo. Ne uporabljajte tekočih čistil.
- Prezračevanje: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
- Povezave: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
- Zdravje baterije: Monitor the health of your battery bank. A weak battery can affect inverter performance.
- Test GFCI: Test the GFCI outlets monthly to ensure proper function.
