Electrical Diagram for Enclosure Leakage Current Test
7.1.3.3.2 Patient Leakage Current Test
This test performs a leakage current test
under single fault conditions (S.F.C.) de-
pending on domestic power outlet of 115
or 230 V AC as source into the floating
inputs.
In all cases, the leakage current is
measured from input jack of the unit
being tested to ground.
Connect the unit being tested to your Safety Tester.
Referring to the electrical diagram, measurements have to be done under the fol-
lowing conditions:
* Polarity switch NORM and RVS
* GND switch GND closed
*
