The inductors of the SISO LCL/LC filter have thermal relays and Pt100 temperature sensors. The relays and sensors are installed on the
surface of winding L2/V and the DC winding.
Alarm temperature limit: 110 °C (230 °F)

1.
Install the thermal relay and Pt100 temperature sensor wires to the drive side inductor.
See the terminal locations in
a.
Connect the alarm relay for AC phase windings to terminals 1.1 and 1.2.
b.
Connect the fault relay for AC phase windings to terminals 2.1 and 2.2.
c.
Connect the alarm relay for DC windings to terminals 1.3 and 1.4.
d.
Connect the fault relay for DC windings to terminals 2.3 and 2.4.
e.
Connect the sensor for AC phase windings to terminals 3.1 and 3.2.
f.
Connect the sensor for DC windings to terminals 4.1 and 4.2.
2.
If the grid side inductor is included in the delivery, install the thermal relay and Pt100 temperature sensor wires to it.
