PV Array Connections
To make the connections from the PV array/combiner to DC interface
enclosure:
1. Follow the lock-out and tag-out procedures on page viii.
2. Open the door of the DC interface enclosure.
3. Route the POSitive (PV+) and NEGative (PV-) PV array conductors through
the conduit to the DC interface enclosure and enter through the opening on
the bottom.
4. The DC power conductors should be terminated at the PV+ and PV-
terminals. Polarity must be observed. See Figure 3-9.
5. Terminations for the POSitive, NEGative, and PV array frame ground
conductors within the DC interface enclosure are made using the 12 mm
screw bolts. Conductors must be provided with crimp-on ring terminals or
compression lugs. Torque the M12 bolts per Table A-6 on page A–5.
6. Close the door of the DC interface enclosure.
