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 S2-6 (POS/DC+), and
K2-6T3 (NEG/DC-) and TB4 (PV Gnd) locations. See Figure 3-19.
4.
Terminations for the S2-6, K2-6T3, and TB4 terminals are made with box
connector using a 1/2" Hex Allen screw. The hardware should be tightened to
a torque value of 600 in-lbs (67.8 Nm).
5.
Close the door to the DC Interface Enclosure and replace the door clamps.
