Prerequisites
Fig. 3 Measurement circuit for measuring the device leakage current using the residual current procedure
in compliance with DIN VDE 0751-1:2001-10, Fig. C6 for Protection Class I.
1 = System
2 = Applied part (if present)
3 = Measuring arrangement (integrated in measuring instrument)
If the direct measurement of the device leakage current is used
(measuring arrangement according to Fig. 3), then the system must be set up insulated
during the measurement and must not be touched during the measurement.

2 = Applied part (if present)
3 = Measuring arrangement (integrated in measuring instrument)
WARNING

Electric voltage!
Noncompliance can lead to severe injuries and even death.
In the direct measurement of the device leakage current (measu-
ring arrangement according to Fig. 2) the protective conductor is
no longer connected with the protective conductor of the power
socket. In the first case of fault, voltages up to the level of the line
voltage can therefore occur on the protective conductor / housing
of the system.
Housing parts of the system must not be touched during the mea-
surement.
Third-person access to the system must be prevented.
