  • Page 6: Safety Rules

    INSTALLATION! RISK OF ELECTRIC SHOCK! 9000.emf The solar inverter VACON 8000 SOLAR has been designed to be installed in enclosed places. It shall be protected against harsh weather conditions. The solar inverter VACON 8000 SOLAR can only be opened by qualified technicians. Inside the in- vert-er module, there is no element which can be fixed or adjusted by the user.
  • Page 7: Earthing And Earth Fault Protection

    The Vacon 8000 Solar inverter must always be earthed with an earthing conductor connected to the earthing terminal marked with The touch current of Vacon 8000 Solar exceeds 3.5mA AC. According to EN62109-1, one or more of the following conditions for the associated protective circuit shall be satisfied:...
  • Page 8 NOTE: Due to the high capacitive currents present in the AC drive, fault current protective switches may not function properly. Do not perform any voltage withstand tests on any part of Vacon 8000 Solar. There is a certain procedure according to which the tests shall be performed.
