Proper installation is crucial for the safe and efficient operation of your inverter. Refer to local electrical codes and standards.
4.1 Ibi
- Install the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials.
- 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 Onirin
All wiring must comply with applicable electrical codes and be performed by a qualified electrician.
- Ilẹ: Connect the inverter's chassis ground terminal to a reliable earth ground using appropriate gauge wire.
- Asopọ igbewọle DC:
- Ensure the battery bank voltage jẹ 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.
- Asopọ jade 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).
- Iṣakoso Latọna jijin (Aṣayan): Connect the remote control unit to the RJ45 port or use the green terminal for external ON/OFF control if desired.
5. Awọn ilana Iṣiṣẹ
5.1 Titan / Pa a
- Lati Fi agbara: 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.
- Lati Paarẹ: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.
5.2 LED Atọka
The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:
- Green Green: Indicates normal operation and power output.
- LED ofeefee: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
- LED pupa: 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 Yipada Eto
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. Itọju
Regular maintenance ensures the longevity and reliable operation of your inverter.
