AC cable installation:
• Unscrew the cable gland or the cable clamps and remove the cover
• Introduce the cable with a suitable cross-section
• Connect the earth cable to the designated threaded metal insert or
earth protection terminal
20
following to the sequence illustrated in the
gure. A ring cable lug, suitable for a M6 size threaded insert, must be
xed t
• Connect the Neutral, R, S, T wires to the respective terminals:
- On the AC output terminal block
17
for the Standard wiring box
- Directly to the AC disconnect switch
36
for the -S and -SX wiring box.
Observe the connection sequence of the phases R, S, T indicated on
the label placed near the AC terminals.
In case of using aluminum cables for AC connections, consider that:
- The terminal present on the Standard version accepts the
connection of copper and aluminum cables.
- For -S and -SX versions must be used bimetallic terminals suitable
to coupling the aluminum wires with the internal contacts of the AC
disconnect switch.
• Give each wire a pull test to conrm the connection is secure
• Set the switch b01 based on the conguration of the output connections.

- 3WIRES position. Three wires conguration (R+S+T)
- 4WIRES position. Four wires conguration (R+S+T+Neutral)
• Before connecting the inverter to the distribution grid it is necessary to set
