6.The AC Sense Harness is pre-terminated within the AC interface/transformer assembly and the opposite end is mated with its 9-pin plug to the corresponding 9-pin jack within the Main Inverter Enclosure. See Figure 3-17.

7.Replace the access panels on the front of both the main inverter Inductor Enclosure and the Transformer Enclosure. Additionally, close the front door to the Main Inverter Enclosure.

To connect the utility service to AC Interface Enclosure:

1.Remove the door clamps and open the door to the AC Interface Enclosure.

2.Route the AC power conductors A, B, C phase, neutral, and a neutral ground cable through the conduit from the utility service to the AC Interface Enclosure. See Figure 3-18 for the location of these terminals.

3.Connect the AC power conductors at the S1-2T1 (A phase), S1-4T2

(B phase), and S1-6T3 (C phase) terminals using the M8 (PV100S-480) or M10 (PV100S-208) hardware. Cables to these terminals must use a crimp-on type ring terminal or compression-type lug. Torque these connections to

115 in-lbs (13.0 Nm) for the M8 (PV100S-480), and 310 in-lbs (35.0 Nm) for the M10 (PV100S-208). See Figure 3-18 for the location of these terminals.

CAUTION: Equipment Damage

The termination points of the AC power conductors at S1 include a captive nut and plastic insulator between the terminals and the panel. Ensure the length of the connection hardware used to attach the AC power conductors at S1-2T1, S1- 4T2, S1-6T3, does not bottom out to the plastic insulator. The depth of the hole at terminals of S1 is ½" from top of the tab. Failure to observe this may result in failure of the plastic insulator and may cause a direct short to ground.
