3.5 Preliminaries to Electrical Connections
WARNING: The electrical connections can be done only after
AURORA is firmly mounted to the wall.
WARNING: The connection of AURORA to the electrical distribution
grid must be performed only by skilled operators and after having
received authorization from the utility that operates the grid.
WARNING: For further details on each single step, carefully read and
follow the “step-by-step” instructions of this section (and sub-sections),
as well as all safety warnings. Any operation non-complying with the
instructions below can lead to operator/installer hazards and to
equipment damage.
WARNING: Always respect the nominal ratings of voltage and current
defined in chapter 8 (Technical Characteristics) when designing your
system. In particular, regarding the photovoltaic system:
¾ Maximum Dc array input voltage to MPPT circuit: 600Vdc in any
condition.
¾ Maximum Dc array input current for MPPT circuit: 10Adc in any
condition.
WARNING: Make sure that your installation design is in compliance
with national wiring methods and local standard regulations, if more
stringent.
WARNING: Carefully protect the photovoltaic panels from the sun
radiation (preferably with dark film or tissue) during the installation
procedure. The protection must be removed once the installation is
completed.
NOTE: The inverter shall be connected ONLY to a dedicated branch
circuit. According to the typical assembly diagram (see Fig.10) the array
must be connected to a Dc disconnect. An AC disconnecting mean with
overcurrent protection must be used to connect AURORA to the grid.
Recommended ratings for the Ac overcurrent protection device is 10A,
240V.
