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 either the L3 or L4 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 L3 or L4 inductor.
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 TB12. 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-lb (47.5 Nm).
