2. אמצעי בטיחות
Failure to follow these instructions may result in death, serious injury, or significant property loss.
- ודאו תמיד שספק הכוח מנותק לפני ביצוע כל חיווט או תחזוקה.
- Never connect the U/V/W output terminals to the AC power supply. Doing so will cause severe damage to the inverter.
- Do not install the inverter in environments with flammable or explosive gases, as this poses a risk of explosion.
- The ground terminal (GND) of the inverter must be properly and securely grounded.
- Only qualified professionals should perform internal wiring or open the inverter's casing due to the presence of high voltage.
