For current transformers: Connect primary winding in series with the line. Secondary terminals are 1S1 and 1S2 for the main winding; if a protection winding exists, use 2S1-2S2. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary winding at one point. Ensure correct polarity for metering and protection.
