5. Telîmatên Operating
5.1 Hêzdarkirin/Off
- Hêzdarkirin: 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.
- Ji bo Veqetandinê: Disconnect all AC loads from the inverter. Flip the main power switch to the 'OFF' position.
5.2 Nîşaneyên LED
The inverter features 3-color LED status indicators on the control panel (refer to Figure 4) to provide operational feedback:
- LED kesk: Indicates normal operation and power output.
- LED zer: Indicates a warning condition, such as low battery voltage or high temperature. The inverter may continue to operate but requires attention.
- LED sor: 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 Mîhengên Guhestina 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. Maintenance
Regular maintenance ensures the longevity and reliable operation of your inverter.
