4.3.3 Enclosure Leakage Current

NOTE:
The circuit diagram is based on the Fluke 601Pro series safety Analyzer.
This measures leakage current of exposed metal parts of Device under test (DUT) and parts of the
system within the patient environment; normal and reversed polarity using S2 test performed both
in normal condition and single fault conditions.
Normal condition (NC): with S1, S3, S5 closed, S2, S4 variable.
Single fault condition (SFC): S1, S3 open (one for each time) and S5 closed, S2, S4 variable.
Allowable value:
Normal condition: 100µA (IEC/EN60601-1)
Single fault condition: 500µA (IEC/EN60601-1)
Normal condition: 100µA (UL60601-1)
Single fault condition: 300µA (UL60601-1)
