5. Nastavení a instalace

Proper installation is crucial for the safe and reliable operation of the VFD. Ensure all safety precautions are followed before proceeding.

5.1 Montáž

• Mount the VFD in a clean, dry, and well-ventilated area, away from direct sunlight, excessive heat, moisture, and dust.
• Ensure sufficient clearance around the VFD for proper airflow, especially around the heat sink and cooling fans.
• Avoid mounting on flammable surfaces.

5.2 Zapojení

All wiring must be performed by a qualified electrician and in accordance with local electrical codes.

1. Příkon (L, N): Connect the single-phase AC 220V power supply to the 'L' and 'N' terminals.
2. Výkon motoru (U, V, W): Connect the single-phase AC motor to the 'U', 'V', and 'W' terminals. For single-phase motors, typically two of these terminals are used, or specific wiring instructions for your motor should be followed.
3. Zem (GND): Connect the ground terminal to a reliable earth ground. This is critical for safety.
4. Ovládací terminály: The VFD includes additional control terminals for external control signals (e.g., start/stop, speed reference). Refer to the detailed wiring diagram for specific connections.
