5. Konfiguracja i instalacja
Proper installation is critical for the performance and safety of the inverter. It is highly recommended that installation be performed by a certified electrician or qualified technician.
5.1 Montaż
- Choose a dry, well-ventilated, and cool location.
- Mount the inverter securely to a stable surface, ensuring adequate clearance for airflow around the cooling fins.
- Avoid mounting near flammable materials or in direct sunlight.
5.2 Podłączenie wejścia prądu stałego
- Ensure the DC power source (battery bank) is rated for 24VDC.
- Use appropriately sized cables to minimize voltage drop and ensure safe current handling.
- Connect the positive (+) terminal of the inverter to the positive terminal of the battery bank.
- Connect the negative (-) terminal of the inverter to the negative terminal of the battery bank.
- Install an external DC fuse or circuit breaker between the battery and the inverter for protection.
5.3 Podłączenie wyjścia AC
- The inverter features a hardwire AC outlet. Connect your AC loads directly to this terminal.
- Ensure all AC wiring complies with local electrical codes.
- Nie należy przekraczać znamionowej mocy wyjściowej falownika.
5.4 Uziemienie
- Connect the inverter's chassis ground terminal to a reliable earth ground point.
6. Instrukcja obsługi
6.1 Włączanie/wyłączanie
- After all connections are secure, switch on the external DC circuit breaker (if installed).
- Locate the main power switch on the inverter's rear panel and switch it to the 'ON' position.
- The LED indicators will illuminate, indicating the inverter's status.
- To power off, switch the main power switch to 'OFF', then disconnect the DC power source.
6.2 Wskaźniki LED
The 3-color LED indicators provide visual feedback on the inverter's operational status and any potential faults.
- Zielony: Normalna praca.
- Żółty: Warning (e.g., low battery, overload warning). Refer to troubleshooting.
- Czerwony: Fault (e.g., overload shutdown, over-temperature shutdown). The inverter will shut down.
6.3 Output Frequency and Voltage Wybór
The inverter allows for selection of output frequency (50/60 Hz) and voltage via DIP switches. Consult the label near the DIP switches for specific settings. Ensure the inverter is off before adjusting DIP switches.
7. Konserwacja
Regularna konserwacja zapewnia optymalną wydajność i długą żywotność falownika.
- Czyszczenie: Periodically clean the exterior of the inverter and ensure cooling vents are free from dust and debris. Use a dry, soft cloth. Do not use liquid cleaners.
- Znajomości: Annually inspect all DC and AC connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
