Information on measuring the 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 has already been determined and documented in the leakage
current report. The measuring procedure was also recorded.
The measurement was performed with the recorded line voltage 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 previous information), a mea-
suring procedure can be selected (direct measurement or differential measurement).
Measurement of the leakage current according to the differential current method (mea-
surement setup according to
is not dangerous to the person performing the measurement and other persons.

General maintenance information
During maintenance, the leakage current measurement must be
conducted and recorded as a repeat measurement.
However, the first measured value must be newly determined and
a new report be must created under the following conditions:
- Lack of documentation for leakage current measurement
- Deviation of the local line voltage from the line voltage document-
ed in the report (e.g., location change/operator change)
- When a different procedure for measuring the leakage current
than the one documented in the report is used.
For the purpose of traceability, reference to the new report must be
written in the old report. The reason for newly determining the first
measured value must be documented and confirmed with a name
and signature.
Electrical voltage!
Non-compliance can lead to severe injury and even death.
The leakage current measurement may be performed on
systems of protection class I only after the protective
conductor test has been passed.
