The TSC 900 can accept 4 x 0-5Aac current inputs from the secondary windings of current
transformers (CT’s). CT’s are to be connected on the load side of the ATS (Phase A, B, C & N).
Wiring of CT primary and secondary windings must be done in strict accordance with schematic
diagram to ensure the correct phasing on 3 phase systems.

energized as severe high voltages can develop which may
cause personal injury or death.
Current sensing connections for the most common applications are shown in the following
