Paigaldage inverter kuiva, hästi ventileeritavasse kohta, eemale otsesest päikesevalgusest, soojusallikatest ja tuleohtlikest materjalidest.
Ensure sufficient clearance around the inverter for proper airflow, especially around the cooling fan vents.
Mount the inverter securely on a stable, non-combustible surface.
Avoid areas where dust, moisture, or corrosive fumes are present.

4.2 Juhtmestik

All wiring must comply with applicable electrical codes and be performed by a qualified electrician.

Maandus: Connect the inverter's chassis ground terminal to a reliable earth ground using appropriate gauge wire.
DC sisendi ühendus:
- Ensure the battery bank voltage on 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.
Vahelduvvoolu väljundühendus:
- 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).
Kaugjuhtimispult (valikuline): Connect the remote control unit to the RJ45 port or use the green terminal for external ON/OFF control if desired.

5. Kasutusjuhised

5.1 Sisse-/väljalülitamine

Sisselülitamiseks: 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.
Väljalülitamiseks: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.

5.2 LED indikaatorit

The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:

Roheline LED: Indicates normal operation and power output.
Kollane LED: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
Punane 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 DIP-lüliti sätted

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. Hooldus

Regular maintenance ensures the longevity and reliable operation of your inverter.

Puhastamine: Puhastage inverteri välispinda regulaarselt kuiva lapiga. Veenduge, et ventilatsiooniavad oleksid tolmust ja prahist vabad. Ärge kasutage vedelaid puhastusvahendeid.
