    Safety rules DANGER! “DANGER!” indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word must be limited to the most extreme situations. This signal word is not used for hazards relating to property damage unless there is also a risk of personal injury appropriate to this level.
  • Page 6 General Remarks For information about where the safety instructions and warning signs are (continued) located on the machine, please refer to the section of your machine’s in- struction manual headed “General Remarks”. Any malfunctions which might impair machine safety must be remedied immediately before the machine is switched on.

  • Page 72: Status Diagnosis And Repair

    It is thus possible to quickly ascertain de- fects in the FRONIUS IG unit, in the photovoltaic system as well as instal- lation and operation errors.

  • Page 73: Complete Failure

    Should the no-load voltage of the modules (at the connecting points of the FRONIUS IG UNIT) not reach 160 V, it is possibly the case of a defect in the remaining part of the photovoltaic system.

  • Page 74: Class 1

    Service codes of service class 1 appear mostly only temporarily, their cause lies in the public mains network. The first reaction of your FRONIUS IG unit is to disconnect from the mains. Subsequently the mains network will be checked for the duration of the observation period stipulated.

  • Page 75: Class 2

    Class 2 service codes are also related to the parameters of the mains network. Some of the checking procedures therefore overlap with those of service class 1. Your FRONIUS IG unwill react in the same way as in the case of service codes in service class 1.
