If pushed, the RD2 must enter thealarm status.The “reset” pushbutton allows the residual currentrelay to return to the starting condition.OEPM0295If the configuration is not appropriate, the devicewill automatically consider as valid the firstconfiguration (according to the diagram) andenter the maximum safety.Technical details ........................ pag. 10/101 Overall dimensions ...................... pag. 12/25ABB5/11
