d.
Insert the DC cable through the DC connector nut on the
metal terminal and press the terminal with professional
crimping pliers (pull the cable to check if the terminal is
well connected to the cable), as shown in Fig. 24:
Fig. 24. Crimping the cable.
e.
Insert the positive and negative cables into the
corresponding positive and negative connectors, pull the
DC cable to make sure that the terminal is well connected
to the connector.
f.
Use an open-end wrench to screw the nut all the way in
and make sure that the terminal is sealed well, as shown
in Fig. 25:
Use the special wrenches for
MC4 connectors to ensure
that the correct tightening
torque is applied, without
damaging the connectors.

Before assembling the DC connector, make sure that
the cable has the correct polarity.
Warning
USER MANUAL
To ensure an optimal connec-
tion, use an approved tool to
crimp the terminals.
Use a multimeter to measure the DC input string
voltage, check the polarity of the DC input cable,
Warning
and make sure that the voltage of each string is
within the 600 V range.
See the "Input" section in Tab. 15.
3.
Connect the cables to the inverter as shown in the following
connection diagrams:
a.
Connection for installations with
solar field (panels in the same direction and
strings of equal length):
Solar panels that make up a string must have the
same technical characteristics.
Connect the strings to each of the unit's inputs, taking
into account the input limits specified in the section
"9. Technical features." The following diagram is
a connection example for a 4 to 12 kW unit:
