INSTALLATION AND
PROGRAMMING INSTRUCTIONS

DANGER
Make sure that the MCCB is open and the earth connector (PE) is
properly earthed.
CAUTION
Do not connect any photovoltaic generator capable of producing a field
voltage exceeding the maximum allowable rating (845 V). If a voltage
exceeding the maximum allowable rating is applied to the inverter, failures
may occur on the internal circuits.
DANGER
The voltage produced by the photovoltaic generator radiated by
sunlight (even weak sunlight) can reach 845 V.
Strictly comply with the national and local safety standards in force in
the installation site.
Cable stripping and wiring must be carried out with extreme care
using proper tools.
Always take EXTREME CARE to avoid any unintentional contacts with
the free pole from the PV generator. Contact with both polarities leads
to severe injury or death due to electric shock.
The specifications of the PV field and the wiring cable dimensioning are given in the table below.

NOTE
The maximum peak power of the PV generator
should not exceed the
value given in the table. Exceeding values do not entail malfunctions to the
inverter, as the equipment automatically limits the power fed into the grid.
However, in this way the PV generator is not exploited at its best.
The voltage at the maximum power point of the PV generator, under the
intended conditions of operation (min/max radiation, min/max temperature
of the modules) must be within the
operating voltage range of the PV
generator.
The maximum rated voltage of the PV field
must never be exceeded. A
higher voltage will damage the equipment in an irreversible manner.
DANGER
When testing the photovoltaic field, do not exceed 500 V for the
isolation test
in order not to damage the integrated varistors protecting the
DC input of the inverter.
