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.
