Perform electrical safety tests using an electrical safety analyzer according to IEC 60601-1, UL
60601-1, EN 60601-1 or CSA C22.2 No. 601.1. The schematics in this section provide a general
understanding of the test equipment. Actual configuration of test equipment may vary. Refer to
the instructions delivered with the safety analyzer to perform each test.
The patient monitor being tested should be placed on an insulating surface.
NOTE: Before proceeding, make sure that all test equipment is properly calibrated, maintained
and functioning.
NOTE: GE recommends that the qualified personnel performing the tests should record the test
results of each electrical safety test, for example by using the installation / maintenance check
forms included in this manual.
System setup
These instructions are intended for every component in the system. Ensure that all system
components are properly connected to the patient monitor.
8.2.2 Power outlet
Verify that the power outlet is wired correctly according to the country’s electrical code
standard before starting the following electrical safety tests. The results of the following tests
will be inaccurate unless a properly wired power outlet is used.
8.2.3 Power cord and plug
Verify that the power cord being used with the patient monitor is good. To do this, check the
following:
•
Inspect the power cord for wear or damage regularly. If damage is suspected, test for
continuity through each conductor of the power cord connector. Replace the power cord,
as necessary, with a regulatory approved cord for the country of use.
WARNING Use only AC power cords recommended or manufactured by GE.
8.2.4 Ground (earth) integrity
Listed below are two alternative methods for checking the ground (earth) integrity: “a) Ground
continuity test” and “b) Impedance of protective earth connection” . These tests determine
whether the device's exposed metal and power inlet's earth (ground) connection has a power
ground fault condition.
Perform either test a) or test b) in accordance to your local regulations.
NOTE: Refer to the instructions delivered with the safety analyzer to perform each test.
a) Ground continuity test
The measuring device (MD) in the diagram below may be a digital multimeter or part of the
safety analyzer.
