Routine veri cation / inspection (routine test report) 32-33. Step 4. Manufacturer's marking 34. Step 5. Declaration of EC conformity (check lists for the manufcturer of an assembly ) 35. Documentation 36-37. 3. Why a Guide to practice? There is a precise conformity on the content of the Standard 61439 Guide 61439 for the practice: in the IEC and EN world of standards . Consequently this document 5 steps to a standard-conforming switchgear assembly uses the writing IEC 61439 / EN 61439 in the following. The Guide lists the process of Design , assembly and documentation IEC 61439 / EN 61439 - of a low-voltage switchgear assembly in the order of the necessary New tasks and responsibilities for the electrician steps and at the same time assigns to these steps the relevant sections from the standard IEC 61439 / EN 61439 .

4 IEC 61439 / EN 61439 shows how a low-voltage switchgear The application of the Guide is focused on the manufacturing assembly , which is safe for the user, can be built. In addition to of distribution boards up to 630 A and in addition to checklists changes affecting the Design of an assembly , the manufacturer of a and instructions regarding the veri cation of compliance with the switchgear assembly is faced with new tasks and responsibilities. maximum temperature rise. De nes which documents belong to a low-voltage switchgear assembly and which veri cations need to be maintained. Makes statements regarding the rating of the assembly so that a Design veri cation can be maintained. The Guide can be downloaded from: w Step 1.

Declaration of CE conformity (check lists). HENSEL, as the system manufacturer, supports panel builders with this Guide to Design and assemble safe low-voltage switchgear assemblies according to IEC 61439 / EN 61439 . 4. Basics of IEC 61439 / EN 61439 . Legal Basis of LVD 2014/35/EU*. In the European Union, the Compliance with this legal basis is con rmed by the declaration Low Voltage Directive LVD of conformity by the manufacturer of a switchgear assembly . 2014/35/EU forms the legal Reference to EN 61439 implies that the basic requirements of the EU only basis for all electrical equipment directive have been met.

Manufacturer's product responsibility The manufacturer is primarily responsible for compliance with the law and the safety of a distribution board!

9 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, HENSEL.
