1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the OUMIFAND SU600 Series Variable Frequency Drive (VFD). The SU600 VFD is designed to convert single-phase 220V input power to three-phase 380V output, enabling precise speed control for three-phase motors ranging from 0.75KW to 5.5KW. Please read this manual thoroughly before using the product.
2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the equipment:
- Electrical Hazard: Ensure all power is disconnected before installation, wiring, or maintenance. Only qualified personnel should perform electrical work.
- Grounding: The VFD must be properly grounded to prevent electric shock.
- Overload Protection: Do not exceed the rated current or power of the VFD and connected motor.
- Environment: Install the VFD in a clean, dry, and well-ventilated area, away from direct sunlight, corrosive gases, and excessive vibration.
- Capacitor Discharge: Wait at least 5 minutes after disconnecting power before touching internal components, as capacitors may retain a dangerous charge.
