Installation

4.Connect the neutral conductor at TB6. Connect the ground conductor at TB2. Terminations for the neutral and ground conductors within the AC Interface Enclosure at the TB6 and TB2 locations are made with 3/8-16" hardware. Cables to these terminals must use a crimp-on type ring terminal or compression-type lug and should be tightened to a torque value of 228 in-lbs (25.7 Nm) for TB6, and 420 in-lbs (47.5 Nm) for TB2 for both the PV100S-480 and PV100S-208 systems. See Figure 3-18 for the location of these terminals.

5.Close the door to the AC Interface Enclosure and replace the door clamps.
