Risk of electric shock or per-sonal injurySafe operation can only be guaranteed if thetransducer is used for the purpose for whichit was designed and within the limits of thetechnical specifications. When this symbolis used, it means you should consult alldocumentation to understand the nature ofpotential hazards and the action required toavoid them.Caution! Risk of hazardous voltageWhen operating the transducer, certain partsmay carry hazardous live voltage (e. g. pri-mary conductor, secondary terminals). Thetransducer should not be put into service ifthe installation is not complete.
