4.0 DC Connections from the PV Array and AC Connections to
WARNING: All electrical installations shall be performed in accordance with all local and
national electric codes.
WARNING: 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. (Note that this is reversed for systems using the positive grounded
option.)
AC and DC (PV) Connections:
The PVI 3000S-5300 inverters are equipped with covered holes and knockouts to fit conduit
fittings that are NEC code-compliant for use with several sizes of rigid and flexible metallic or non-
metallic conduit. All conduit and wiring installation is done in the wiring box. This design allows
installation and wiring of the inverter to be done without opening the main inverter enclosure
which should not be opened during installation. AC & DC terminals allow for #10 to #6 AWG
copper conductors.
