- Avoid mounting in areas with excessive dust, moisture, or direct heat sources.
6.2 Wiring Connections
Refer to the wiring diagram on the unit and the following instructions for connections.
Figure 6.1: Rear view of the VFD with connection terminals.
This image shows the rear panel of the ViaGasaFamido A2-8030 VFD. Clearly visible are the input power terminals labeled "POWER" and the output motor terminals labeled "MOTOR". The input specifies "Single phase input 220V connection R and T", indicating where the single-phase AC power should be connected.
- Power Input (R, T): Connect the AC 180-250V single-phase or three-phase power supply to the input terminals labeled 'R' and 'T'. Ensure the power source matches the VFD's specifications.
- Motor Output (U, V, W): Connect the three-phase motor to the output terminals labeled 'U', 'V', and 'W'. Do not connect AC power directly to these terminals.
- Grounding: Connect the ground terminal of the VFD to a reliable earth ground.
- Control Wiring: If using external control signals (e.g., potentiometer for speed control, external start/stop buttons), refer to the detailed wiring diagram in the included physical manual for specific terminal assignments.
6.3 Initial Power-Up
- Before applying power, double-check all wiring connections for correctness and security.
- Ensure no loose wires or foreign objects are inside the VFD.
- Apply power to the VFD. The display should illuminate.
- Observe for any error codes or unusual behavior.
