ELECTRICAL CONNECTION
DANGER
Before handling any cable, make sure, using suitable instruments, that there is no
dangerous voltage.
WARNING
The connection of AURORA to the electrical grid must be carried out only by qualified
operators and only after having received authorisation from the electricity company that
administrates the mains.
11.1.
Preliminary operations for the electrical connection
For details of each single operation to be carried out, the instructions given in this chapter (and in
its sub-chapters) and all the safety warnings must be read carefully and followed step by step.
Any operation which does not
comply with these instructions could
create a situation of danger for the
operator/installer and damage the
appliance.
It is extremely important and
opportune
to
disconnect
the
photovoltaic field before making the
connection to the inverter by means
of the upstream DC switches, since
there could be high voltages capable
of generating conditions of serious
danger.
Always respect the nominal voltage
and current characteristics, when
designing your own system. In
particular, always keep in mind the
following
with
regard
to
the
photovoltaic system:
•
Maximum array DC voltage input to
each of the MPPT circuits found
under any conditions.
•
Maximum array DC current input to
each of the MPPT circuits found
under any conditions.
