2.4.2 Earth leakage current
NOTE:
The earth leakage current test must be carried out with reversed and non-reversed power plug.
Enter the highest value.
NOTE:
Make sure that power supply leads, accessories and system configuration correspond to the
previous tests. Insulated installation of the devices is required.
2.4.2.1 Earth leakage current N.C. (IEC)
(normal condition)
Test value to IEC 60-601: less than/equal to 500 μA
2.4.2.2 Earth leakage current N.C. (UL)
(normal condition)
Test value to UL 2601-1: less than/equal to 300 μA
2.4.2.3 Earth leakage current S.F.C. (IEC)
(single fault condition, PEN conductor interrupted)
Test value to IEC 60-601: less than/equal to 1000 μA
2.4.2.4 Earth leakage current S.F.C. (UL)
(single fault condition, PEN conductor interrupted)
Test value to UL 2601-1: less than/equal to 300 μA
2.4.2.5 Earth leakage current N.C. reversed (IEC)
(normal condition, power plug reversed)
Test value to IEC 60-601: less than/equal to 500 μA
2.4.2.6 Earth leakage current N.C. reversed (UL)
(normal condition, power plug reversed)
Test value to UL 2601-1: less than/equal to 300 μA
2.4.2.7 Earth leakage current S.F.C. reversed (IEC)
(single fault condition, PEN conductor interrupted, power plug reversed)
Test value to IEC 60-601: less than/equal to 1000 μA
2.4.2.8 Earth leakage current S.F.C. reversed (UL)
(single fault condition, PEN conductor interrupted, power plug reversed)
Test value to UL 2601-1: less than/equal to 300 μA
2.4.3 Patient leakage current test
NOTE:
The patient leakage current test must be carried out with reversed and non-reversed power plug.
Enter the highest value. This test can be implemented internally on most of the testers.
NOTE:
Make sure that power supply leads, accessories and system configuration correspond to the
