8. AC Output connection
WARNING –
B
To prevent electrocution hazards, open and lock
out the external AC disconnect switch before connecting the AC
conductors, and any time the AC wiring box cover is to be removed.
Proper PPE is required. AC output overcurrent protection is not
provided with the inverter; it is the responsibility of the end user to
provide overcurrent protection for the AC output circuit. To reduce
the risk of fire, connect only to a circuit provided with an overcurrent
protection in accordance with the NEC (ANSI/NFPA 70). The inverter
must be connected only to a dedicated branch circuit provided with
the maximum branch overcurrent protection device (OCPD) listed in
the technical data sheet at the end of this document. Size conductors
per the NEC, Article 310 - use 90°C copper wire only; conductors
must be sized according to operating temperature range and
continuous current ratings. The AC grid wiring is connected through
the inverter switchbox. AC output wire must be listed PV wire rated
minimum 600V.
• Run an approved raceway between the inverter and external AC
disconnect switch.
• Pass the AC wires throught the openings dedicated to the AC conduit.
ATTENTION –
A
When complete, seal conduit with water-tight fittings
to maintain the NEMA type 4X enclosure rating. Installer should
follow conduit manufacturers’ guidelines and best practices.
• Determine which AC output is applicable for the inverter model being
installed. The AC wiring connections based on the AC grid type are shown
in the table (also found on a label in the wiring box).

This is a single phase inverter. Use the wiring schemes shown on the
table below when a different grid standard is used. Refer to the
instruction manual to properly set the inverter grid standard from the
front panel display. Use 90°C copper wire only. Refer to the instruction
manual for wiring instructions.

• Connect wiring to the numbered terminals based on selected grid type.
AC wiring terminals are spring pressure type and accommodate a wire
size range of 20-6 AWG.

WARNING –
B
The default 240V split-phase connection requires
the grid Neutral to be connected to the inverter for proper operation.
Before connecting the inverter to the grid, the grid type must be
selected during the commissioning phase. If several inverters are
installed to a three-phase AC grid, always distribute the inverters
between the phases in order to reduce power imbalance between
the phases.
• When all connections are complete, reinstall the front covers and tighten
the cover screws with 1.5Nm (13.2 in-lbs) torque.

10. Commissioning
ATTENTION –
A
Before proceeding with commissioning, make sure
you have carried out all the operations and checks indicated in the
previous sections of this quick installation guides, and verify that the
inverter cover
(05)
was properly closed!
READ THE MANUAL –
E
Refer to the product manual for further
information about the configuration and the use of the functionality
of the internal Webserver. Consult the product manual for more
information.
Commissioning and configuration of the inverter can be made using a
wireless capable device such as a smartphone, tablet or laptop.
The steps for commissioning are listed below:
• Set the inverter’s DC disconnect switch
(16)
and any external DC switches
to “ON” position: If the input voltage applied to one of the two input channels
is greater than the minimum starting voltage, the inverter will start up.
ATTENTION –
A
The inverter is powered ONLY by the voltage coming
from the photovoltaic generator: the presence of grid voltage alone IS
NOT SUFFICIENT to allow the inverter to power up. If an RSD device
is installed on the plant, the inverter will power-up only if both AC and
DC are supplied!
• Set the external AC disconnect switch downstream to the inverter to “ON”
position.
