These tests measure leakage current of the device's floating inputs
(patient connections ground).
This test measures leakage current from the floating input (patient
connection) to ground during normal condition (N.C.) and single fault
condition (S.F.C). In all cases, the leakage current is measured from the
floating input to ground: The device has to be turned on and off, and
connected to your safety testing instrument.
During N.C., measurements should be taken under the following
conditions (refer to "Electrical Safety Tests"
Device in ON state

Polarity switch NORM and RVS

GND switch GND closed

S1 (neutral) closed

During S.F.C., measurements should be taken under the following
conditions (refer to "Electrical Safety Tests"
Device in ON state

Polarity switch NORM and RVS

GND switch closed, S1 (neutral) open

GND switch open, S1 (neutral) closed
