}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.

Safetyfeatures

Therelaymeetsthefollowingsafetyrequirements:

}Thecircuitisredundantwithbuiltinselfmonitoring.

}Thesafetyfunctionremainseffectiveinthecaseofacomponentfailure.

}Highsignalatinputcircuit(e.g.lightguardnorinterrupted):Thesafetycontactsare

closedandthesemiconductoroutputtransmits.

}Lowsignalattheinputcircuit(e.g.lightguardisinterrupted):Thesafetycontactsare
