10-6-3 Leakage Current Limits
In accordance with these standards, fault conditions like Reverse Polarity of the supply mains and Open
Neutral are no longer required for field evaluation of leakage current. Because the main source of
leakage current is the mains supply, there are different acceptance limits depending on the
configuration of the mains (100-120 or 230-240).
Compare all safety-test results with safety-test results of previously performed safety tests (e.g.
CAUTION
last year etc). In case of unexplainable abrupt changes of safety-test results consult
experienced authorized service personnel or GE for further analysis.

*ISO (on Dale 600) and Mains Applied (on Dale 601) refer to the sink leakage test where mains (supply)
voltage is applied to the part to determine the amount of current that will pass (or sink) to ground if a
patient contacted mains voltage.
