Typical Wiring Diagrams
First pass and carefully dress one external load wire through the on-
board CT (L1). Then connect the ac supply and load wires to TB1 as
shown. If required, verify that correct line-power polarities are applied
to the external load (see Technical Note 4). Ensure all wires are
stripped and terminals torqued correctly. For proper operation, pass
only one load wire through the on-board CT’s center hole.
