Non recommandé pour
For current transformer (CT) wiring: Connect primary busbar through the window. Secondary terminals are 1S1 and 1S2 for the main winding; if dual ratio, additional taps may be present. Ensure secondary is never open-circuited while energized - hazardous voltage can occur. Ground the secondary circuit at one point only, preferably at the CT terminal box, to ensure safety and proper operation. Follow IEC 61869-2 and IEEE C57.13 for terminal markings and connections.
