1. Power Off: Confirm that all power sources are disconnected before making any electrical connections.
2. Input Power (L, N): Connect the single-phase 220V AC power supply to the input terminals labeled 'L' and 'N'.
3. Motor Output (U, V, W): Connect the three-phase motor to the output terminals labeled 'U', 'V', and 'W'. Ensure correct phase sequence for desired motor rotation.
4. Grounding (E): Connect the ground terminal (E) to a reliable earth ground. This is critical for safety.
5. Control Wiring (Optional): If external control signals (e.g., start/stop, speed reference) are used, refer to the detailed wiring diagram in the full product manual for specific terminal connections.
6. Double Check: Verify all connections are secure and correct before applying power.
