TYPICAL WIRING DIAGRAMS
First pass and carefully dress one output wire from the external CT
through the on-board CT (L1). Then connect the ac supply 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 a single wire through the on-board CT's center hole.
