For CT secondary wiring, ensure terminals 1S1 and 1S2 are used for the main secondary winding. If a protection winding is present, use 2S1 and 2S2. Never open-circuit the secondary of a CT while energized - hazardous voltage may occur. Ground the secondary circuit at one point only. Follow IEC 61869-2 for terminal markings and safety requirements.
