The system must be switched on during the 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 protocol.
This value must not exceed the permissible leakage current values of 2.5 mA according
to DIN VDE 0751-1:2001-10, Table F.1, line "System leakage current for devices
according to remarks 1 and 3".
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 measure-
ment 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.
The evaluation is not necessary in the case of a new determination.
File the protocol sheet in the system folder or log book.
Electrical voltage!
Non-compliance can lead to severe injuries and even death.
No housing parts of the system may be touched during the direct
measurement of the system leakage current (measuring arrange-
ment according to Fig. 3).
Access to the system by third parties must be prevented.
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding mainte-
nance procedures or safety checks.
A sudden or unexpected increase of the measured values may
indicate that a fault has occurred in the primary circuit of the
power supply (damaged insulation, damage caused by humidity,
defective interference suppressor, etc.) - even if the limit value of
2.5 mA is not exceeded.
