oad protection switch (AC disconnect switch)
It is recommended that the inverter AC connection line be fitted with a
device to protect against maximum current and leakage to ground, with
the following characteristics:

onnection to the AC side terminal block
To avoid risks of electrical shock, all wiring operations must be carried out with the disconnect
switch downstream of the inverter (grid side) off.
For all the models the connection is made with the AC output terminal block
25
by passing the cables through the AC cable gland
48
.
Strip 10mm of sheathing from the cables to connect to the AC grid, then
insert into the inverter the AC line cable, making it pass through the AC cable
gland
48
; the maximum diameter of the cable accepted by the cable gland
is from 10 to 17 mm².
Connect on the cable gland
25
the ground cable (yellow-green) to protect
against contact marked by the symbol , the neutral cable (usually blue)
to the terminal marked by the letter
N
and the phase cable to the terminal
marked by the screen-print
L1
; every individual terminal of the terminal
block accepts a cable with maximum section of 16 mm² (It is necessary
to fix the AC cables to the terminal block with a tightening torque of at
least 1,5 Nm).
Once the connection to the terminal block has been made, firmly screw
the cable gland (7.5 Nm tightening torque) and check the tightness.
