Connect primary busbar through the window. Secondary terminals: 1S1 and 1S2 for metering (if dual ratio, 2S1-2S2 for protection). Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary circuit at one point. Follow IEC 61869 / GB/T 20840 for wiring and safety.
