Thesafetyrelayprovidesasafetyrelatedinterruptionofasafetycircuit.
Thefollowingisdeemedimproperuseinparticular:
}Anycomponent,technicalorelectricalmodificationtoaproduct
}Useofaproductoutsidetheareasdescribedintheproductdocumentation
}Anyusethatisnotinaccordancewiththedocumentedtechnicaldetails.
Foryoursafety
}Onlyinstallandcommissiontheunitifyouhavereadandunderstoodtheseoperating
instructionsandarefamiliarwiththeapplicableregulationsforhealthandsafetyatwork
andaccidentprevention.
