General Information
The determined values, including the measuring points, must be recorded and assessed
in the protective conductor resistance report.
The measuring procedure and the measuring device used (designation and serial num-
ber) are also to be documented.
1.7.1
Information on measuring the system leakage current
NOTE
Observe the instructions in the safety rules for installation and repair (ARTD-002.731.17
...).
WARNING
First measured value
The first measured value was already determined and documented in the system leakage
current report. The measuring procedure was also recorded.
The measurement was performed with the recorded line voltage, line frequency and with
the recorded measuring equipment.
Measurement
Perform the measurement according to DIN VDE 0751, part 1 (see ARTD-002.731.17....),
and record the determined value.
The measuring procedure indicated in the report must be used.
If the first measured value has to be newly determined (see note), a measuring procedure
can be selected (direct measurement or differential measurement).

The system leakage current measurement is to be conducted and
recorded as the repeat measurement during maintenance.
However, the first measured value must be newly determined and
a new report must created under the following conditions:
Lack of system leakage current measurement documentation
Local line voltage or line frequency deviating from the line voltage
and line frequency documented in the report (e.g., in the event of
a site/operator change)
Use of a different procedure for measuring the system leakage cur-
rent from the one documented in the report.
For the purpose of traceability, reference to the new report is to be
written on the old report. The reason for newly determining the
first measured value is to be documented and confirmed with a
name and signature.
Electrical voltage!
Non-compliance can lead to severe injuries and even death.
The system leakage current measurement may be per-
formed on systems of protection class I only after the
protective conductor test has been passed.
