2. Sikkerhedsforanstaltninger
Failure to follow these safety instructions may result in death, severe injury, or property damage.
- Sørg altid for, at strømforsyningen er afbrudt, før du udfører ledningsføring eller vedligeholdelse.
- Do not connect the U/V/W output terminals directly to the AC power supply. This will cause internal damage to the inverter.
- The inverter must not be installed on flammable surfaces or near flammable materials to prevent fire hazards.
- Ensure the ground terminal of the inverter is properly and securely grounded.
- Avoid installation in environments containing explosive gases to eliminate explosion risks.
- Only qualified professionals should perform wiring and internal inspections. The converter contains high voltage components; do not open the shell casually.
