4.2 Ožičenje
All wiring must comply with applicable electrical codes and be performed by a qualified electrician.
- Ozemljitev: Connect the inverter's chassis ground terminal to a reliable earth ground using appropriate gauge wire.
- DC vhodna povezava:
- Ensure the battery bank voltage je 12VDC.
- Use appropriately sized cables for the DC input to minimize voltage drop and ensure safety. Refer to cable sizing charts based on current and distance.
- Connect the positive (+) terminal of the battery bank to the red (+) terminal on the inverter.
- Connect the negative (-) terminal of the battery bank to the black (-) terminal on the inverter.
- Install a DC-rated fuse or circuit breaker between the battery bank and the inverter's positive terminal, as close to the battery as possible.
- Priključek izhoda AC:
- Connect your AC loads to the hardwire AC output terminal block.
- Ensure the total load does not exceed the inverter's continuous power rating (3000W).
- Daljinski upravljalnik (izbirno): Connect the remote control unit to the RJ45 port or use the green terminal for external ON/OFF control if desired.
5. Navodila za uporabo
5.1 Vklop/izklop
- Za vklop: Ensure all DC and AC connections are secure. Flip the main power switch on the inverter's rear panel to the 'ON' position. The Power LED indicator should illuminate.
- Za izklop: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.
5.2 LED indikatorji
The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:
- Zelena LED: Indicates normal operation and power output.
- Rumena LED: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
- Rdeča LED: Indicates a fault condition, such as overload, short circuit, or severe over/under voltage. The inverter will shut down to protect itself and connected devices.
5.3 Nastavitve stikala DIP
The DIP switches on the control panel allow for customization of certain inverter parameters, such as output voltage, frequency, and power saving mode. Refer to the detailed specifications table (Figure 5) or the product datasheet for specific configurations. Always adjust DIP switches when the inverter is powered off.
6. Vzdrževanje
Redno vzdrževanje zagotavlja dolgo življenjsko dobo in zanesljivo delovanje vašega inverterja.
- Čiščenje: Zunanjost pretvornika redno čistite s suho krpo. Prepričajte se, da so prezračevalne odprtine brez prahu in umazanije. Ne uporabljajte tekočih čistil.
- Povezave: Regularly check all electrical connections (DC input, AC output, ground) for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Pregled baterije: Inspect batteries for signs of damage, corrosion, or electrolyte leakage. Ensure battery terminals are clean and tight.
- Okolje: Preverite, ali delovno okolje ostaja znotraj določenih temperaturnih in vlažnostnih območij.
