Page 5: Location Selection And Installation Position
Location selection and installation position Safety Rules Ex- WARNING! Indicates a possibly dangerous situation. Death or serious injury may planation result if appropriate precautions are not taken. CAUTION! Indicates a situation where damage or injury could occur. Minor injury or damage to property may result if appropriate precautions are not taken. NOTE! Indicates a possibility of flawed working results and possible damage to the equipment. -
Page 6: Intended Use
Only put the inverter into operation with the fixing screws securely tightened. NOTE! Fronius will not bear any costs for loss of production, or installations, etc., which may arise due to a detected electric arc and its consequences. Fronius accepts no liability for fires which may break out despite integrated arc detection/interruption (e.g., due to a parallel arc). - Page 7 The inverter is suitable for indoor installation. The inverter is suitable for outdoor installation. Because of its NEMA 4X protection class, the inverter is not susceptible to hose water on any side and can also be operated in moist environ- ments.

Page 8: Installation Position Of The Inverter
The inverter is designed to be dustproof in principle. However, in areas of high dust accumulation, the cooling surfaces can become dusty, which can impair the thermal performance. In this case, the dust must be re- moved regularly. We therefore recommend that installation is not carried out in areas and environments with high dust accumulation (e.g., iron fil- ings) as this can cause damage to the inverter. -
Page 9: General Location Selection
Do not install the inverter with the connections upwards on a vertical wall or column. Do not install the inverter overhanging with the connections upwards. Do not install the inverter overhanging with the connections downwards. Do not install the inverter on the ceiling. General location Please note the following criteria when choosing a location for the inverter: selection... -
Page 10: Example: Installation Of Several Inverters
When installing the inverter in a switch cabinet or similar closed environment, it is neces- sary to make sure that the hot air that develops will be dissipated by forced-air ventilation. If you wish to install the inverter on the outer walls of cattle stables, it is important to keep a minimum clearance of 2 m between all sides of the inverter and air vents and other openings. -
