Electrical Safety Checks - GE CAM-14 Service Manual

Electrical Safety Checks

1. Conduct current leakage and ground continuity tests.
Perform electrical safety checks when indicated in the preceding table. All
indicated electrical safety checks require a pass/fail indication for the steps
performed. Record the measurement values in your debrief. Refer to
Tests" on page 19
2. Conduct the dielectric withstand test.
Refer to
Leakage Tests
The leakage tests are safety tests to ensure that the equipment poses no electrical
health hazards. Use the following table to determine which tests apply to the unit
under test and the maximum allowable leakage currents. For international leakage
limits, refer to the internal standards agencies of that particular country.
If the unit under test fails the leakage tests, do not allow the customer to use the
equipment. Call GE Healthcare Customer Support for assistance.
GE Healthcare recommends that you perform these tests with the following frequency:
• Before applying power for the first time
• Every year as part of routine maintenance
• Whenever internal assemblies are serviced
You need a leakage tester to perform the leakage tests.
NOTE:
The accuracy of the leakage tests depends on a properly-wired wall outlet. Do not
proceed until you verify the integrity of the power source.
WARNING:
Total system leakage current must not exceed 100 microamperes.
