Load 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:
PVI-6.0-TL-OUTD PVI-8.0-TL-OUTD PVI-10.0-TL-OUTD PVI-12.5-TL-OUTD
Type Automatic circuit breaker with differential thermal magnetic protection
Voltage rating 400 Vac
Current rating 16 A 16 A 20 A 25 A
Magnetic protection
characteristic
B/C
Type of differential
protection
A/AC
Differential sensitivity 300 mA
Number of poles 3/4
Connection 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 inverter models, connection is carried out using the AC output termi-
nal block
15
passing the cables internally through the AC cable gland
11
.
Remove the protective lm located on the hole to be used for the AC
cables
11
, insert the M40 cable gland in the hole and secure it using the
M40 lock nut (to ensure environmental protection IP65 it is necessary
to x the cable gland to the inverter chassis with a minimum tightening
torque of 8.0 Nm).
Strip 10 mm of sheathing from the AC grid connection cables then plug
the AC line cable into the inverter, passing it through the previously in-
stalled cable gland; the maximum diameter accepted by the cable gland
is from 19 to 28 mm².
Connect on the terminal block
15
the protective earth (yellow-green) ca-
ble to the contact labelled with the symbol, the phases cables to the
terminals labelled with the letters R S T and in case of star connection,
connect the neutral cable (normally blue) to the terminal labelled with the
letter N.
Each terminal of the terminal block accepts a cable with cross-section
which can vary from 0.6 up to 16 mm² (The AC cables must be tightened
on the terminal block with a minimum torque of 1.5 Nm). Pay special at-
tention and ensure you do not reverse any phases with the neutral!
Once the connection to the terminal board has been made, tighten the
cable gland rmly (tightening torque 5.0Nm) and check the seal.
