12.5 OPERATING CONDITIONS OF THE EUT
1. Setup the EUT and Test Equipment as shown on 12.3.
2. Power on the EUT. Acting performance checking program to allow EUT executing its usual
operation mode during test.
12.6 TEST PROCEDURE
The EUT and its load were placed on a table which was 0.8 meters height.
For AC Power line test:
The EUT was connected to the power mains through a coupling device that directly couples
to the Voltage Dips and Interruption Generator.
Voltage dips of >95% for 10ms and 30% for 500ms were applied to the EUT three times with
10 sec intervals between dips. A power interruption of 100% for 5000ms (5 sec) was applied
to the EUT three times with 60-second intervals between interruptions.
