For current transformers, connect primary conductor through the window. Secondary terminals: 1S1-1S2 for metering winding, 2S1-2S2 for protection winding. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary winding at one point. Follow IEC 61869-2 terminal markings.
