oad protection switch (AC disconnect switch)
To protect the AC connection line of the inverter, we recommend install-
ing a device for protection against over current and leakage with the fol-
lowing characteristics:
UNO-2.0-I-OUTD
UNO-2.5-I-OUTD
Type
Automatic circuit breaker with differential thermal magnetic protection

onnection to the AC side terminal board
To prevent electrocution hazards, all the connection operations must be carried out with the
disconnect switch downstream of the inverter (grid side) open and locked.
For all models you connect the AC
output screw terminal block
09
by
passing the cables through the AC cable gland
08
.
The maximum diameter accepted by the cable gland is from 10 to 17
mm2 while each terminal of the terminal board accepts a cable with
cross-section which can vary from 0.6 up to 16 mm2.
Unscrew the AC cable gland
08
, remove the cover, insert the cable of
suitable cross-section and connect the conductors (Ground, Neutral, and
Phase) to the terminals on the AC
output screw terminal block
09
.
Pay special attention and ensure you do not reverse the phase with
the neutral!
Once the connection to the terminal board has been made, tighten the
cable gland firmly and check the seal.
Before connecting the inverter to the distribution grid it is necessary to
set the country standard by manipulating the two rotary switches a09 and
following the instructions in the table displayed in the relevant section.v
NOTE: For installations carried out in Italy it is required to lead seal the AC connector. To this
end a bracket must be fixed on top of the
AC output screw terminal block 09 by tightening the
screw on the appropriate turret is provided. The distributor grid during the phase of connect-
ing to the grid will then provide for application of the lead sealing.
