WARNING:
All electrical installations shall be done in accordance with all local
electrical codes and the National Electrical Code (NEC), ANSI/NFPA 70.
The negative DC, Photovoltaic connection is grounded within the inverter through
the ground fault detection and interrupt circuit (GFDI). The PV negative should not
be grounded at any other point in the system. The PV positive must never be
grounded at any time.
When conduit hubs are used on the AC and DC disconnect boxes in an outdoor or
wet location, rain-tight or wet location hubs that comply with the requirements in
the Standard For Fittings For Conduit and Outlet Boxes, UL514B, are to be used.
For AC, 3-phase wiring, use 6 AWG, (recommended for the 208VAC version)
minimum 90

F), copper wire for connection with the inverter’s 3-phase AC
disconnect. (8 AWG recommended for the 480VAC version.) Torque terminal
screws to 45-50 in- lb. Voltage drop and other considerations may dictate that larger
wire sizes be used. (A maximum of 2 AWG copper conductor wire, and 4 AWG
copper ground wire can be used, but verify that any wire size choices meet NEC
requirements)
For DC/PV wiring with the integrated, fused PV combiner (with 10-15 Amp fuses),
use 12 AWG minimum 90
