Conformity

This product complies with the directive of the Council of the European

Communities on the approximation of the laws of the Member States relating to

electromagnetic compatibility (EMC Directive 2004/108/EC) and concerning

electrical equipment for use within specified voltage limits (Low-voltage directive

2006/95/EC). This conformity is the result of tests conducted by ABB in

accordance with the product standards EN 50263 and EN 60255-26 for the EMC

directive, and with the product standards EN 60255-1 and EN 60255-27 for the low

voltage directive. The IED is designed in accordance with the international

standards of the IEC 60255 series.
