Wiring - Specific

PV Array Connections

To make the connections from the PV Array/combiner to DC Interface enclosure:

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

2.Route the PV Array cables conductors POSitive (PV+), NEGative (PV-), and PV GND through the conduit to the DC Interface Enclosure, entering on the underside.

3.The DC power conductor terminations are made at the TB3-1 (POS/DC+), and TB3-2 (NEG/DC-) and TB3-3 (PV Gnd) locations. See Figure 3-19.

4.Terminations for the POSitive, NEGative, and GND conductors within the DC Interface enclosure at the TB3 locations are made with box connector using a 7/16" Hex Allen screw. The hardware should be tightened to a torque value of 500 in-lbs. (56.5 Nm) for both the PV100S-480 and PV100S-208 systems.

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