Repeat measurement
In the case of maintenance or repairs, perform the protective conductor resistance mea-
surement again.
Document and assess the values determined in the repeat measurement.
The measurement must be performed according to DIN VDE 0751, Part 1 (see ARTD
Part 2). In this case the protective conductor resistance for all touchable conductive parts
must be measured during the normal operating state of the system.
Make sure that control cables or data cables between the components of the system are
not mistaken for a protective conductor connection.
During the measurement, the power cable and additional connection cables with the inte-
grated protective conductor (e.g. monitor cable between the basic unit and monitor trolley)
must be moved section by section to detect cable breaks.
The protective conductor resistance must not exceed 0.2 ohms.
The values determined in the repeat measurement, including the measuring points, must
be recorded and assessed in the protective conductor resistance report.
