Table 9-14: Abnormal Frequency Transient

This test will set the voltage at 115V and will remain at this voltage through out the test except for the
A(CF) category. The test will cycle the frequency three times as shown in Table 9-14. Each repeat will
start from sequence 2. Test 1 and Test 2 for the A(CF) category are done in succession as a single
test.
