CT connections for both ABC and ACB phase rotations are identical, as shown in the Typical Wiring Diagram.
The exact placement of a zero-sequence core balance CT to detect ground fault current is shown as follows. Twisted-pair
cabling on the zero-sequence CT is recommended.

The phase voltage channels are used for most metering and protection purposes. The auxiliary voltage channel is used as
input for the synchrocheck and volts-per-hertz features, which are optional features available for some UR models.
