Indicates a situation where damage could occur. ▶ If not avoided, minor injury and/or damage to property may result. NOTE! Indicates a risk of flawed results and possible damage to the equipment. -
Page 7: Environmental Conditions
Only operate the device if all of its protection devices are fully functional. If the protection devices are not fully functional, there is a danger of: Injury or death to the operator or a third party Damage to the device and other material assets belonging to the operator Any safety devices that are not functioning properly must be repaired by a suitably quali- fied technician before the device is switched on. -
Page 8: Backup Power
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 disconnection on the utility side and deactivation of the replacement power mode by opening the integ- rated DC disconnector on the inverter. - Page 9 The text and illustrations are all technically correct at the time of printing. We reserve the right to make changes. The contents of the operating instructions shall not provide the basis for any claims whatsoever on the part of the purchaser.
