Connect primary through the window. Secondary terminals: 1S1 and 1S2 for metering (if provided), 2S1 and 2S2 for protection (if provided). Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary circuit at one point only, preferably at the switchgear earth bar. Ensure shorting links are closed before removing the CT from service.
