5. Setup and Installation
5.1 Unpacking
Carefully remove the inverter from its packaging. Inspect for any signs of damage during transit. The package should contain: 1 x Single to 3 Phase Converter, 1 x Manual.
5.2 Mounting
- Mount the inverter vertically on a stable, non-flammable surface.
- Ensure adequate ventilation around the unit to prevent overheating. Maintain sufficient clearance from other equipment.
- Avoid mounting in direct sunlight, high temperature, high humidity, or dusty environments.
5.3 Wiring
All wiring must be performed by a qualified electrician. Ensure power is disconnected before wiring.
- Grounding: Connect the inverter's GND terminal to a reliable earth ground.
- Power Input: Connect the single-phase AC220V 50/60Hz power supply to the R and S (or T) input terminals.
- Motor Output: Connect the three-phase motor to the U, V, and W output terminals.
- Control Wiring (Optional): If using external control signals (e.g., start/stop buttons, potentiometers for speed control, RS485 communication), connect them to the appropriate control terminals as per your application requirements. Refer to the detailed wiring diagram in the full manual for specific connections.
Note: This inverter does not support external resistors. If your motor load is heavy, consider choosing an inverter with a higher power rating.

8. Troubleshooting
This section provides solutions to common issues. For complex problems, contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on. | No input power; faulty wiring; internal fuse blown. | Check power supply; verify wiring connections; consult a technician for fuse replacement. |
| Motor does not start. | Incorrect parameters; motor wiring error; overload. | Check motor parameters (frequency, voltage); verify motor wiring (U, V, W); reduce load or check motor for issues. |
| Overload error displayed. | Motor drawing excessive current; inverter undersized for load. | Reduce motor load; check motor for mechanical issues; consider a higher-rated inverter if load is consistently heavy. |
| Abnormal noise from inverter or motor. | Loose connections; motor issues; incorrect frequency settings. | Check all wiring connections; inspect motor; verify frequency settings. |
