Connecting current and voltage inputs

Connect the wires from the CTs to the correct device according to the phase order and the
connection diagram. Each terminal for CTs is dimensioned for one 10 Gauge wire or for two wires
of maximum 12 Gauge.
To help connecting the current and voltage inputs, the connector pair is marked with symbols. For
a current input, the connector pair forms a circle. But in the case of a voltage input, the connector
pair forms two half-circles.
