replaced by Section 11.2.
11.7.Test Procedure
1) Set up the EUT and test generator as shown on Section 11.2.2.
2) For line to line coupling mode, provide a 1kV 1.2/50us voltage surge (at
2) For line to line coupling mode, provide a 1kV 1.2/50us voltage surge (at
open-circuit condition) and 8/20us current surge to EUT selected points, and for
active line / neutral line to ground are same except test level is 2kV.
active line / neutral line to ground are same except test level is 2kV.
3) At least 5 positive and 5 negative (polarity) tests with a maximum 1/min
repetition rate are applied during test.
4) Different phase angles are done individually.
5) Record the EUT operating situation during compliance test and decide the EUT
5) Record the EUT operating situation during compliance test and decide the EUT
immunity criterion for above each test.
