  • Page 5: Location Selection And Installation Position

    Location selection and installation position Explanation of DANGER! Indicates an immediate danger. Death or serious injury may result if Safety Instruc- appropriate precautions are not taken. tions WARNING! Indicates a possibly dangerous situation. Death or serious injury may result if appropriate precautions are not taken. CAUTION! Indicates a situation where damage or injury could occur.

  • Page 6: Intended Use

    Only put the inverter into operation with the fixing screws securely tightened. NOTE! Fronius will not bear any costs for production downtimes, or for installa- tions, 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.

  • 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.

  • Page 11: Attaching The Mounting Bracket

    Attaching the Mounting Bracket Safety WARNING! An electric shock can be fatal. Danger of residual voltage from ca- pacitors. Wait until the capacitors have discharged. Discharge takes five minutes. CAUTION! The inverter can be damaged by soiling or water on the terminals and contacts of the connection area.

(15 mm) AC ~ max. 80 A ≥ 100 mA ΔN § National Standards Type A If AC cables are laid over the shaft of the DC main switch or across the DC main switch connection block, the cables may be damaged when the inverter is pivoted or the inverter may not be able to be pivoted.

  • Page 22: Maximum Ac Fuse Protection

    100 mA is generally sufficient in this case. However, false alarms can be triggered for the residual current circuit breaker type A in individual cases and depending on local conditions. For this reason, Fronius recommends that you use a residual current circuit breaker suitable for frequency converters.

    Maintenance and service work on the inverter power stage set should only be carried out by Fronius-trained service technicians. WARNING! An electric shock can be fatal. Inadequately sized electrical compo- nents can cause serious injury and damage to property.

  • Page 26: General Information About Solar Modules

    Note the temperature coefficients in the solar module data sheet More exact data for sizing the solar module for the particular location can be obtained using calculation tools such as the Fronius Configuration Tool (available at https:// www.solarweb.com). See NEC table 690.7 for the appropriate voltage adjustment factor for crystalline sili- con solar modules, or use the manufacturer’s specified voltage coefficients.

  • Page 27: Connecting Solar Module Strings To The Inverter (Dc)

    NOTE! Take into account local specifications when configuring cable cross sec- tions. Connection Requirements: Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife. IMPORTANT Do not use brushes, files or sandpaper. Aluminum particles may get stuck and can transfer to other cables.
