REV 5
7–3 ELECTRICAL SAFETY TESTS
The following tests are performed at the factory and should be performed at the site. These tests are: grounding conti-
nuity, chassis leakage current, probe leakage current, and ECG leakage current. All measurements are made with an
Electrical Safety Analyzer Model Dale 600/600E built by Dale Technology Corporation or equivalent device.
Note
In GEMS–America region, it is NOT necessary to do the leakage current test when installing the
LOGIQ 400 systems on condition that no optional devices are installed with the console. For more
details, contact your regional service support center.

NAME DESCRIPTION
46–285652G1 Electric Safety Analyzer DALE 600 For 120V Units
46–328406G2 Electric Safety Analyzer DALE 600E For 220V Units
2113015 Leakage Current Ultrasound Kit For 120V and 220V Units
7–3–1 Outlet Test Wiring Arrangement
Test all outlets in the area for proper wiring arrangement by plugging in the Dale 600/600E and noting the combination
of lights that are illuminated (Refer to ILLUSTRATION 7–3).
OUTLET TEST
ILLUSTRATION 7–3
Note
No outlet tester can detect the condition where the Neutral (grounded supply) conductor and the
Grounding (protective earth) conductor are reversed. If later tests indicate high leakage currents, this
should be suspected as a possible cause and the outlet wiring should be visually inspected.
