WARNING
Electrical voltage!
Non-compliance can lead to severe injuries and even death.
No housing parts of the system may be touched during direct mea-
surement of the system leakage current
.
¹
Third-person access to the system must be prevented.
The system must be switched on during measurement. Measuring devices with auto-
mated measuring sequences must therefore be set to manual measurement.
The highest value must be entered in the system leakage current report.
This value must not exceed the permissible leakage current values according to DIN VDE
0751-1:2001-10, Table F.1, line "System leakage current for devices according to
remarks 1 and 3", of 2.5 mA.
Measure and record the current line voltage. If the measured line voltage deviates from
the nominal voltage, correct the measured value to the value corresponding to a mea-
surement at the nominal value of the line voltage. This is also to be documented.
Document the measuring procedure (differential measurement or direct measurement)
and the measuring device used (designation and serial number).
In the case of repeat measurements, the measured value must also be evaluated.
NOTE
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding maintenance
procedures or safety checks.
A sudden or unexpected increase of the measured values may in-
dicate that a fault has occurred in the primary circuit of the power
supply (damaged insulation, damage caused by water ingress or
humidity, defective interference suppressor, etc.) - even if the limit
value of 2.5 mA is not exceeded.
The evaluation is not necessary in the case of a new determination.
File the report sheet in the system folder or log book.
