– Special Case, Single Fault: Voltage at Applied Parts
Schematic Diagram
Voltage is activated between PE at the test socket/DUT and the
applied parts.
Wiring Diagram
Direct Measuring Method
–
Measurement type: permanent connection P1
– Permanent connection
– Probe to P1 terminal
Schematic Diagram
Patient leakage current is measured between the short-circuited
patient terminals (test probe P1) and PE at the mains connection.
Power is supplied to the DUT via the DUT’s permanent connec-
tion. The device under test (PC1) is operated with mains power.
The fault condition
Normal State is shown here.

Wiring Diagram
Direct Measuring Method
–
Measurement type: permanent connection APP
– Permanent connection
– APPs to APP sockets
Schematic Diagram
Patient leakage current is measured between the applied parts
connected to the APP sockets at the test instrument and PE at
the mains connection.
Power is supplied to the DUT via the DUT’s permanent connec-
tion. The device under test (PC1) is operated with mains power.
Accessible conductive parts which are not connected to the
housing must be contacted with test probe P1.
