Indicates a potentially harmful situation. ▶ Minor injury or damage to property may result if appropriate precautions are not taken.
Page 10 Safety CAUTION! Danger from crushing due to the incorrect handling of attachments and con- nection parts. Injuries to limbs may result. ▶ Use the integrated grips when lifting up, putting down, and attaching the inverter. ▶ When fitting attachments, ensure that no limbs are located between the attachment and the inverter.
Page 11 Where an automatic backup power supply is installed, a backup power warning notice (https://www.fronius.com/en/search-page, item number: 42,0409,0275) must be fitted on the electrical distributor. Maintenance and installation work in the home network requires both disconnec- tion on the utility side and deactivation of the replacement power mode by open- ing the integrated DC disconnector on the inverter.
Page 12 Depending on the insolation conditions and the battery state of charge, the backup power supply is automatically deactivated and activated. This can cause the backup power supply to unexpectedly return from standby mode. Therefore, installation work can only be performed on the home network when the backup power supply is deactivated.
