System with multiple socket: 0. Insulation measurement must not carried
out, excluded the accompanying documents according the manufacturer's specifications.2 Visual inspection inspection
Check for visible damages the following:
- connecting cables plug-and-socket connections
- housing
- strain relief, protection against bending and kinking .3. Here, possible refer recommendations the manufacturer previously measured values.
* Note Particular requirements" might allow other leakage current values.
* Note the current issue the DIN VDE 0751-1 standard, the measurement the insulating resistance required, considered tobe convenient. Measuring results, analysis, evaluation, documentation (inspection and preparation for intended use)
* Note The DIN 62353 (VDE 0751-1):2008-08 standard does not contain any measuring methods and admissible values for devices generating leakage currents.BENNING BENNING 750 A
