2. Safety Instructions
WARNING: Improper installation or operation can lead to serious injury or property damage. Always follow these safety guidelines.
- Ensure power is disconnected before any wiring or maintenance.
- The VFD must be properly grounded to prevent electrical shock.
- Do not connect U/V/W output directly to AC power supply; this will damage the inverter.
- Install the inverter in a non-flammable, dry environment, free from explosive gases.
- Only qualified professionals should perform wiring and installation.
- Do not open the VFD casing; internal components are under high pressure and can cause injury.
- The VFD features a 10-layer protection system, including overcurrent, overload, overvoltage, phase loss, and short circuit protection. However, these are supplementary and do not replace safe operating practices.
