Disconnect the 2 thick wires (normally black and
blue) from the inverter contactor (CFI) that come
from the mainswitch.
Put the small wires back on the contactor
terminals.
3-ph inverter (3x380-480V without N only):
Disconnect the 3 wires (normally black) from the
inverter contactor (CFI) that come from the
mainswitch.
1-ph inverter :
Connect these wires to terminals U1 and V1 of
the AC-reactor.
3-ph inverter :
Connect these wires to terminals U1, V1 and W1
of the AC-reactor.
1-ph inverter :
Connect terminals U2 and V2 to the inverter
contactor by new wires, to the same terminals
where you have disconnected the 2 other wires.
Terminals W1 and W2 of the AC-reactor will not
be used if the inverter is 1-phase.
3-ph inverter :
Connect terminals U2,V2,W2 to the inverter
contactor by new wires, to the same terminals
where you have disconnected the 3 other wires
Make sure to attach and connect all wirings so
that they can not be damaged.
Place the AC-reactor on a suitable place in the
machine.
The most easy is to mount it in the corner of the
back panel, but it has the small disadvantage
that you always need to disconnect the wires if
you want to open the back panel.
Drill 4 holes (diam. 10mm) and fix the ACreactor with the included bolts and nuts.
Make sure that no burs from the drilling can
enter the frequency inverter or other
components.
Disconnect the 2 wires (normally blue and black)
from the mainswitch that go to the filter.
3-ph inverter (3x380-480V without N only):
Disconnect the 3 wires (normally black) from the
inverter contactor (CFI) that come from the
mainswitch.
1-ph inverter :
Connect these wires to terminals U2 and V2 of
the AC-reactor.
3-ph inverter :
Connect these wires to terminals U1, V1 and W1
of the AC-reactor.
1-ph inverter :
Connect terminals U1 and V1 of the AC-reactor
to the mainswitch by new wires, to the same
terminals where you have disconnected the 2
other wires.
Terminals W1 and W2 of the AC-reactor will not
be used if the inverter is 1-phase.
3-ph inverter :
Connect terminals U2,V2,W2 to the inverter
contactor by new wires, to the same terminals
where you have disconnected the 3 other wires
Make sure to attach and connect all wirings so
that they can not be damaged.
5) Remarks:
If you have a machine with a transformer for the control circuit, this transformer fulfills the same protection
function as the AC-reactor. It means that the AC-reactor is only necessary in the circuit of the inverter, it is not
necessary to put the AC-reactor also in the circuit of the control circuit (but it is allowed).
