11. Electrical Safety Testing of the SLE4000
This test is performed using an approved electrical safety testing device.
The electrical safety test must be carried out on the unit with all the electrical connections
intact.
Connect the ventilator to the electrical safety tester and turn the unit ON.
Connect the flow sensor connector via a test loom to the electrical safety tester.
Perform the tests.
Equipment under test is: SLE4000 Infant Ventilator Class 1B (flow sensor is a Floating type
applied part).
Check that in all the preceding tests: the resistance to earth on the internal metal screening
is less than 0.2.
