The following procedure is illustrated in Figure 3-4. If there is more than one PV

string, label the positive and negative wire pairs appropriately (for example:

PV1-String #1 POS, PV1-String #1 NEG, PV1-String #1 GND,

PV1-String #2 POS, etc.).

To wire the PV array to GT Inverter:

1. Remove the wiring/disconnect box cover (see page 3–2).

2. Install DC conduit from the PV string(s) to the GT Inverter wiring box,

through one of the knockout holes.

3. Route the wires from the PV string(s) through the conduit and into the wiring

box.

4. Connect the DC Ground from each PV string to the GROUND bar in the

wiring box.

5. Connect the POSITIVE (+) wire from the PV1 string #1 to one of the PV+

terminals in the wiring box. Double check that the wire is in the proper

location and tighten the screw.

6. Connect the NEGATIVE (–) wire from the PV1 string #1 to one of the

PV– terminals. Double check that the wire is in the proper location and

tighten the screw.

7. Repeat for the PV1 string #2, if there is one.

a) Connect the POSITIVE (+) wire from the PV1 string #2 to the unused

PV+ terminal.

b) Connect the NEGATIVE (–) wire from the PV1 string #2 to the unused

PV– terminal.

Double check that the wires are in the proper locations and tighten the screws.

8. If required, connect the DC ground electrode conductor tot he DC or AC

ground electrode as per NEC 690.47.

9. Ensure all connections are correctly wired and properly torqued according to

values shown in Table 3-1.
