ld be monitored to assure that no unacceptable interactions (degradations or distortions) between redundant safety circuits will occur. • Surges should be applied to power terminals. The guidance of IEEE Std C62.45-2002 is acceptable for surge testing at the power input. • MCFs should also be applied to the output terminals in the differential mode and between any output terminal and ground (common mode); the input should be monitored to assure that no unacceptable interactions (degradations or distortions) between redundant safety circuits will occur. MCFs should be applied to the isolation device for a sufficient duration to allow any measurable effects to occur on the isolation device and to allow monitored values or effects to reach steady-state. BTP 7-11-8 Revision 5 - March 2007 Description of Test Results Test data and results should verify that the design basis faults, including short circuits, open circuits, grounds, MCF, and surge were applied to the device in all of the applicable connection modes (i.e., applicable input, output, power, and ground connection modes). Test data and results should verify that the test acceptance criteria are met. 4. Review Procedures Confirm that the device design conforms to the guidance of Regulatory Guide 1.75. Confirm that the applicant/licensee has established an acceptable test method and that the specified testing addresses the conditions of the intended applications. Confirm that the applicant/licensee’s testing properly applied the MCF and surges to devices under test. Confirm that the acceptance criteria of IEEE Std 603-1991, or IEEE Std 279-1991, and Regulatory Guide 1.75 were met during the tests. C. REFERENCES 1.
