2. Veiligheidsmaatreëls

Failure to follow these instructions may result in death, serious injury, or significant property loss.

• Always ensure the power supply is disconnected before performing any wiring or maintenance.
• Never connect the U/V/W output terminals to the AC power supply. Doing so will cause severe damage to the inverter.
• Do not install the inverter in environments with flammable or explosive gases, as this poses a risk of explosion.
• The ground terminal (GND) of the inverter must be properly and securely grounded.
• Only qualified professionals should perform internal wiring or open the inverter's casing due to the presence of high voltage.

6.1 Basiese werking

1. Krag aan: Ensure all connections are secure, then apply single-phase 220V AC power to the L and N terminals. The VFD display should illuminate.
2. Begin Motor: Druk die RUN button to start the motor. The FWD or REV indicator will light up depending on the current direction setting.
3. Pas Frekwensie/Spoed aan: Use the rotary knob to adjust the output frequency, which in turn controls the motor speed. The display will show the current frequency (Hz) or RPM (r/min).
4. Verander rigting: Druk die FWD/REV button to toggle the motor's rotation direction.
5. Stop Motor: Druk die STOP/RESET knoppie om die motor te stop.

6.2 Parameterprogrammering

Die PROG en FUNC/DATA buttons, along with the arrow keys (▲, ▼), are used to access and modify various operating parameters. Refer to the detailed programming manual (if available) for specific parameter settings relevant to your application.

• Druk PROG to enter or exit programming mode.
• Gebruik ▲ en ▼ to navigate through parameter groups or individual parameters.
• Druk FUNC/DATA to select a parameter for editing or to confirm a value.
• Use the rotary knob or arrow keys to change the parameter value.
• Druk FUNC/DATA again to save the new value.

7. Onderhoud

Regular maintenance helps ensure the longevity and reliable operation of your VFD.

• Skoonmaak: Keep the VFD clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Ventilasie: Ensure that the cooling fans and ventilation openings are not obstructed to prevent overheating.
• Inspeksie: Inspekteer gereeld alle bedradingsverbindings vir styfheid en tekens van slytasie of skade.
• Professionele diens: Due to high internal voltages, any internal inspection or repair should only be performed by qualified service personnel. Do not attempt to open the VFD casinjouself.
