Quick Installation Guide
1
Access to the zones inside the inverter must be carried out with the equipment dis-
connected from the network and from the photovoltaic generator.
Isolate the inverter by externally disconnecting the side AC, DC and any voltages
connected to the multifunction relay. Acting only on switches present on the inverter,
some internal parts have hazardous voltages.
The GROUNDING KIT must be installed inside the DC wiring box.
• Before removing the front cover, place the DC
disconnect switch to OFF position.
In “ON” position, the switch does not allow the
removal of the front cover.
• Proceed to remove the 8 screws holding the
front cover of the DC wiring box.
• The grounding board must be installed on the
appropriate holder positioned on the lower side
of the communication and control card (area
highlighted in the figure to the side).
• Press down lightly on both sides of the
board until the two holding clips will block
the board to the support.
• Connect the signals wiring between the
grounding board and the communication and
control board. One side of the signals wiring
must be connected to the J13 connector on
the grounding board; the other end must be
connected to J1 connector present on the
communication and control board.
• Connect the cable present on the grounding
board to negative pole placing the cable on
the negative connection of the DC disconnec-
tor switch (first terminal at the top right of the
disconnector switch).
Observe the installation sequence shown in
the figure.
- Metallic support (tightening torque 4 Nm)
- Toothed washer
- Cable from the grounding board
- Cutted washer
- Hexagonal nut (tightening torque 4 Nm)
The components required for the fixation of the cable are present in the materials supplied.
• Check the correct installation of the board,
signals wiring and connection cable to the
negative pole
In -SX version of the Wiring Box AC, a cartridge must be removed from the AC overvolt-
age dischargers (as described below)
