5、 EXFS 100 (KU)設(shè)備檢測(cè),EXFS 100,Generally the EXFS 100 (KU) is maintenance-free, an inspection can be made e.g. according to DIN EN 60079-17. The inspection means for example the visual control of the enclosure for damage as well as of the terminals and connecting cables for becoming loose or damage of

6、the insulation the cleaning of the insulating paths and to remove conductive films if necessary (e.g. acc. to IEC 60664-3: 2003-02) the examination of the terminals for contact safety the electrical testing for short-circuiting or sufficient insulation capability (Riso 500 k 250 V).,14.01.08 / 5325e
