16、01 NOTE The application of this standard can involve the selection of components and/or parts that are to be integrated with the electrical equipment of a machine in accordance with the instructions and/or specifications of the manufacturers of the components and/or parts. Also, in the context of le

17、gislative duties that are applicable to machinery manufacturers within the European Union it is important to recognise that the safety of electrical equipment can involve the use of equipment and services provided by other parties (see 3.54). To assist manufacturers in satisfying these duties it can

18、 be necessary for the supplier of the equipment to obtain information about its intended use. This can be facilitated by establishing an agreement between the user and supplier on basic conditions and additional user requirements to enable proper design, application and utilization of the electrical

19、 equipment of the machine. An enquiry form that can be used for this purpose is provided in Annex B. Such an agreement is not intended to reduce the level of safety of the electrical equipment provided by this standard. _ 2 Endorsement notice The text of the International Standard IEC 60204-1:2005 w
