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 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 re-determined (see previous note), it is possible to
select the measuring method (direct measurement or difference measurement).
Measurement of the system leakage current according to the differential current method
(measuring arrangement according to Fig. 3) must be given preference, since no danger
for the person performing the measurement and other persons arises during the measure-
ment.
However, please note the minimum resolution of the leakage current measuring instru-
ment and any additional manufacturer's data restricting the use of the measuring device.
Polymobil 10
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 be must created under the following conditions:
- Lack of leakage current measurement documentation
- Deviation of the local line voltage from the line voltage
documented in the report (e.g., change of location or operator)
- Use of a different procedure for measuring the leakage current
than the one documented in the report.
For the purpose of traceability, reference to the new report must
be written on 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 system leakage current measurement may be performed on
systems of protection class I only after the protective conductor
test has been passed.
