Risk of DangerSafe operation can only be guaranteed if thecurrent switch is used for the purpose it hasbeen designed for and within the limits of thetechnical specification. When this symbol isused, it means you must consult all documen-tation to understand the nature of potentialhazards and the action required to avoid them.Warning! Risk of ShockWhen operating the current switch, certainparts of the module may carry hazardous livevoltage (e.g. primary conductor, controlledload). The switch should not be put into op-eration if the installation is not complete.For products intended for the EU market, the following isapplicable to the CE compliance of the product:The DS3 series comply with EN 61010-1 CAT III 300Vrmsmax. line-to-neutral measurement category. If insulated cable isused for the primary circuit, the voltage rating of the measure-ment category can be improved according to the insulationcharacteristics given by the cable manufacturer. |
