PRECAUTIONS FOR TESTING

sponding supply voltage and each input signal should be kept off state.

After this, the specified ON and OFF level setting for each input signal should be done.

2. When performing “OC” and “SC” tests, the turn-off surge voltage spike at the corresponding protection operation should not

(These test should not be done by using a curve tracer or its equivalent.)
