This test subjects the EUT to power network faults and “brownouts”.  Testing was performed in accordance 
with IEC 61000-4-11.  The standard configuration as outlined in the IEC 61000-4-11 was used.  The EUT is 
powered up to a nominal voltage of 230 VAC 50 Hz, and then software-controlled voltage dips and 
interruptions are introduced.  For further information, please refer to the technical sections of the IEC 61000-
4-11 in addition to the test results section and photographs of the test set-up provided in this report.
