Connect primary terminals P1/P2 in series with the line. Secondary terminals are 1S1/1S2 for the main winding; if dual ratio, use 2S1/2S2 for the second winding. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary winding at one point. Ensure the secondary burden does not exceed 10VA. Follow IEC 61869-2 and IEEE C57.13 conventions.
