Preliminary operations for electrical connection

WARNING: The electrical connection must only be made after the inverter
has been firmly fixed to the wall.
WARNING: The connection from the inverter to the power supply
distribution grid must be performed exclusively 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 them step-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 when designing the
photovoltaic field:
Maximum DC input voltage to each of the two MPPT circuits: 520
Vdc.
Maximum DC input current to each of the two MPPT circuits: 14Adc
(PVI-4.6-I-OUTD), and 12.5Adc (PVI-3.8-I-OUTD).
WARNING: Check the national regulations and local standards, so that
electrical installation complies with them.
In accordance with the assembly diagram, a main isolator, comprised of an automatic
magnetothermic switch should be inserted between the inverter and the distribution
grid, on the AC output side. The characteristics of the main isolator or automatic
switch are 20A 230V for PVI-3.8-I-OUTD, and 25A 230V for PVI-4.6-I-OUTD.
