Preliminary operations for electrical connection

WARNING: The electrical connection can only be made after
AURORA has been firmly fixed to the wall.
WARNING: The connection of AURORA to the power
distribution grid must only be performed by qualified personnel, and
only after authorisation has been received from the power supply
provider managing the distribution grid.
WARNING: For details regarding each individual operation, it is
necessary to read and follow the instructions in this chapter (and sub-
chapters), and all safety warnings. Read the instructions carefully and
follow themstep-by-step. Any operation which does not conform to what
follows may cause hazardous conditions for the operator/installer, and
can cause damage to the equipment.
WARNING: When designing the system, always respect the voltage
and current nominal ratings, as indicated in chapter 8 (Technical
Specifications). The following in particular must be kept in mind with
reference to photovoltaic fields:
Maximum DC voltage input to each of the two MPPT circuits: 520
Vdc.
Maximum DC current input to each of the two MPPT circuits: 24Adc
for PVI-10.0-I, 25Adc for PVI-12.0-I, under any conditions.
WARNING: Check the national regulations and local standards, so that
electrical installation complies with them.
In accordance with the typical assembly diagram, a main isolator, comprised of an
automatic magnetothermic switch, should be inserted between AURORA and the
distribution grid, on the AC output side. The characteristics of the main isolator or
automatic switch are 32A 400V.
