Functional Description
− Foreign DC voltage > +20 V or < -20 V:
Isolation is untestable,
Capacitance is untestable,
Noise is untestable.
Another reason can be that an alarm from a failed line-test has been
cleared by the “Reset Line Test Defects” button in the SUPM1 unit status.
• Not tested
Indicates that this test was not executed and so no test results are availa-
ble.
