2. Veiligheidsinligting
Volg altyd die volgende veiligheidsmaatreëls om die risiko van elektriese skok, brand of besering te verminder.
- Elektriese veiligheid: Moenie die omskakelaar oopmaak nieasing. Daar is geen onderdele binne wat deur die gebruiker onderhou kan word nie. Verwys alle onderhoud na gekwalifiseerde personeel.
- Ventilasie: Verseker voldoende ventilasie rondom die omsetter. Moenie ventilasie-openinge blokkeer nie.
- Omgewing: Install the inverter in a dry, cool, and well-ventilated area, away from flammable materials, corrosive chemicals, and direct sunlight.
- Batteryverbinding: 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.
- Aarding: Properly ground the inverter chassis to a reliable earth ground.
- Laai kapasiteit: Do not exceed the inverter's rated output power (3500W continuous). Overloading can cause damage and fire hazards.
- GFCI Beskerming: The integrated GFCI outlets provide protection against ground faults. Test the GFCI regularly as per local electrical codes.

5. Opstelling en installering
Behoorlike installasie is van kritieke belang vir die omsetter se werkverrigting en veiligheid.
- Montering: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- GS-invoerverbinding:
- 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.
- Maak seker dat alle verbindings styf en veilig is.
- Aarding: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- WS-uitvoerverbinding:
- 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.
- Afstandbeheer (opsioneel): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Belangrik: Always ensure the inverter is OFF before making any connections.
6. Operasie
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Krag aan: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Status aanwysers: 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.
- Koppelladings: Plug your AC appliances into the GFCI outlets. Ensure the total wattagDie e van gekoppelde toestelle oorskry nie 3500W nie.
- GFCI toets: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Kragbesparingsmodus: 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.
- Skakel af: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
7. Onderhoud
Gereelde onderhoud verseker die lang lewensduur en betroubare werking van u omsetter.
- Skoonmaak: Hou die omsetter skoon en vry van stof en puin. Gebruik 'n droë lap om die buitekant af te vee. Moenie vloeibare skoonmaakmiddels gebruik nie.
- Ventilasie: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
- Verbindings: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
- Battery gesondheid: Monitor the health of your battery bank. A weak battery can affect inverter performance.
