Step 3: Connect and apply a 120 Vac, 60-hertz voltage source to terminals C13 (A-phase) and C16
(neutral).
Step 4: Step the frequency of the applied voltage down to 55-hertz. Measure the time delay and record
the result.
Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delays listed in Table 152. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings groups 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 81-2, 81-3, 81-4, 81-5, 81-6, 81-7, and 81-8.
