In Case of Failure
„
Check any broken of the enclosure. Replace any defective part.
„ Inspect wiring for bad crimps, poor connections, or damage.
„ Test the wall outlet; verify it is grounded and is free of other wiring abnormalities.
Notify the user or owner to correct any deviations. As a work around, check the other
outlets to see if they could be used instead.
„ Change another probe to confirm if the fail is caused by console.
„ If the leakage current measurement tests fail on a new unit and if situation can not be
corrected, submit a Safety Failure Report to document the system problem. Remove unit
from operation.
„
If all else fails, stop using and inform the Customer Service Engineer for analysis and
disposal.

A.7 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage,
through a limiting resistance, to selected applied part terminals. Current measurements are
then taken between the selected applied part and earth. Measurements are taken with the
test voltage (110% of mains) to applied parts in the normal and reverse polarity conditions as
indicated on the display.
The following outlet conditions apply when performing the Mains on Applied Part test.
„ Normal Polarity;
„ Reversed Polarity
