Basics of IEC 61439 / EN 61439 Manufacturer's product responsibility The manufacturer is primarily responsible for compliance with the law and the safety of a distribution board! He must provide evidence that the distributor was free of design, manufacturing and instruction errors when brought on the market. Thereby he must prove the safety of the assembly according to the appropriate documents (risk analysis and assessment). These documents must be retained. He must create a declaration of conformity and affix the CE marking visibly. EU only Who is the manufacturer of a switchgear assembly? The new standard clearly regulates the responsibility for a distribution board placed on the market.
It distinguishes between the original manufacturer (system manufacturer) and the manufacturer of the switchgear assembly (panel builder). Panel builder Panel builder Panel builder System manufacturer, e.g. HENSEL Original manufacturer (system manufacturer) Manufacturer of the switchgear assembly (Panel Builder) Responsible for: Responsible for: the distribution board system the rating of the switchgear assembly according to the customer/operator requirements the verification of the design by testing, calculation or construction rules the compliance with the design verification of the original manufacturer the documentation of this design verification, e.g.
test documentation, derivations, calculations the declaration of conformity to the customer (Declaration of Conformity) the creation of tools to design and appropriate instructions for assembling and testing EU only the marking and documentation of the assembly the performance of the design verification and documentation The original manufacturer (system manufacturer) already provides the respective verifi cations for its distribution board system.
Panel builders who have no distribution board system of their own and assemble verifi ed systems into ready-to-connect switchgear assemblies thus decide for themselves about their own verifi cation efforts, as they can use the documents of the original system manufacturer. 6
