4. Fametrahana sy fametrahana
Proper installation is crucial for the safe and efficient operation of your inverter. Refer to local electrical codes and standards.
4.1 Fametrahana
- 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 Tariby
All wiring must comply with applicable electrical codes and be performed by a qualified electrician.
- Fandehanana: Connect the inverter's chassis ground terminal to a reliable earth ground using appropriate gauge wire.
- DC Input Connection:
- Ensure the battery bank voltage dia 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.
- AC Output Connection:
- 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).
- Fanaraha-maso lavitra (tsy voatery): Connect the remote control unit to the RJ45 port or use the green terminal for external ON/OFF control if desired.
5. Torolàlana miasa
5.1 Mamelona/Mamono
- Hamelona: 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.
- Mamono: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.
5.2 LED famantarana
The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:
- LED Maitso: Indicates normal operation and power output.
- LED mavo: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
- LED mena: 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 Fanovana DIP Switch
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. Fikojakojana
Regular maintenance ensures the longevity and reliable operation of your inverter.
- Fanadiovana: Manadio tsindraindray ny ivelany ny inverter amin`ny lamba maina. Ataovy azo antoka fa tsy misy vovoka sy potipoti-javatra ny varavarankelin'ny rivotra. Aza mampiasa mpanadio ranon-javatra.
- Fifandraisana: Regularly check all electrical connections (DC input, AC output, ground) for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Fanaraha-maso ny bateria: Inspect batteries for signs of damage, corrosion, or electrolyte leakage. Ensure battery terminals are clean and tight.
- Tontolo iainana: Hamarino fa mijanona ao anatin'ny mari-pana sy hamandoana voafaritra ny tontolo iasana.
