documentation
(Inspection and preparation for intended use)
*Note 1: The VDE 0751-1:2015-10 (EN/ IEC 62353) standard does not contain any measuring methods and admissible values for
devices generating DC leakage currents. In this case, the manufacturer should provide specifications in the
accompanying documents.
*Note 2: "Particular requirements" might allow other leakage current values.
*Note 3: In the current issue of the VDE 0751-1 standard, the measurement of the insulating resistance is required if it is
considered to be “convenient”. Insulation measurement must not be carried out if it is excluded in the accompanying
documents according to the manufacturer's specifications.
Limits for the insulating resistance are specified in the VDE 0751-1:2015-10 (EN/ IEC 62353) standard. Additionally,
it is possible to refer to recommendations of the manufacturer or to previously measured values.
