Risk of dangerSafe operation can only be guaranteed if thetransducer is used for the purpose for which itwas designed and within the limits of the techni-cal specifications. When this symbol is used,it means you must consult all documentation tounderstand the nature of potential hazards andthe action required to avoid them.Warning! Risk of electrical shockWhen operating the transducer certain parts maycarry hazardous live voltage (e.g. primary con-ductors, power supply). The transducer shouldnot be put into operation if the installation is notcomplete.For products intended for the EU market, the following is ap-plicable to the CE compliance of the product:The VTD series comply with EN 61010-1 CAT III 600 V maxmeasurement category. Power source overvoltage category I asdefined per EN 61010-1
