To make the connections from the PV Array/combiner to DC Interface:
1. Open the door to the DC Interface.
2. Route the PV Array cables conductors POSitive (PV+) and NEGative (PV-)
through the conduit to the DC Interface, entering on the underside.
3. The DC power conductor terminations are made at either the optional Fused
Combiner (GTFC) or TB3, as well as TB4 and TB5 (PV GND). See Figure 3-
11 for the location of the terminals and Table 3-1 for DC Terminal polarity for
each GT100 model.
4. Terminations for the POSitive, NEGative, Ground conductors within the DC
Interface are made using the 10 mm hardware.
5. Close the door to the DC Interface.
