Connecting the DC Wiring
WARNING: Shock hazard
Use caution when working around sources of DC power. Although the DC/AC disconnect switch disconnects the inverter from DC power, hazardous voltages from paralleled PV strings will still be present upstream of the switch and inside the wiring box. To reduce the risk of shock during installation, cover the array with an opaque (dark) material before making any connections, ensure the DC/AC Disconnect Switch is set to OFF (see Figure
Figure
The following procedure is illustrated in Figure
To wire the PV array to the GT Inverter:
1.Connect the POSITIVE (+) wire from the PV1 string #1 to one of the PV+ terminals.
2.Connect the NEGATIVE
3.Repeat for the PV1 string #2, if there is one.
4.Repeat for the PV1 string #3, if there is one.
5.Ensure all connections are correctly wired and properly torqued to a maximum 16
