3.In addition to the power conductors, route the AC Sense Harness assembly (Xantrex P/N 1-152403-01) between the main inverter to the AC interface/transformer assembly. Prior to completing the installation of the AC Sense Harness, secure the harness to the AC power conductors with nylon tie-wraps so it does not touch the surfaces of the L1 inductor. Failure to secure the AC Sense Harness away from these surfaces may cause deformation of the harness insulation and possibly damage due to the excessive heat generated by the L1 inductor.

Prior to completing the installation of the AC Sense Harness, secure the harness to the AC power conductors with nylon tie-wraps.

4.Connect the AC power conductors in the Transformer Enclosure at the T6-X1 (A phase), T6-X2 (B phase), and T6-X3 (C phase) bus bars using

3/8-16" hardware. Connect the ground conductor in the AC Interface/Transformer Enclosure at TB2. Cables to these terminals must use a crimp-on type ring terminal or compression-type lug. Tighten these connections to a torque value of 420 in-lbs (47.5 Nm).
