Ground (Earth) Integrity

Revision A
Maintenance: Electrical Safety Tests
Listed below are required tools and test equipment to perform electrical
safety tests. Equivalent equipment may be substituted as necessary.
Item
Leakage Current Tester
Digital Multimeter (DMM)
Ground Bond Tester
ECG Test Body
Before starting the tests, the wall receptacle from which the device will
get electrical power must be checked. This test checks the condition of
the wall receptacle to ensure correct results from leakage tests.
For international wall receptacles, refer to the internal standards
agencies of that particular country. Use a digital multimeter to ensure
the wall receptacle is wired properly.
If other than normal polarity and ground is indicated, corrective action
must be taken before proceeding. The results of the following tests will be
meaningless unless a properly wired wall receptacle is used.
Listed below are two methods for checking the ground (earth) integrity,
"Ground Continuity Test" and "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 the test method below that is required by your Country/Local
governing safety organization.
