Connecting the LCL filter
By default, the LCL filter is protected against overheating (caused by a faulty fan, for example)
with a thermistor. If the filter temperature becomes too high, the IGBT supply module is
automatically stopped. The thermistor must always be connected to digital input XDI1 on
the control unit.
WARNING!
If the overheating protection is removed with parameter settings, the filter may be
damaged permanently or cause a fire.
Frames R1i…R4i only: The 24 V DC power supply needed for the cooling fan is not included
in the delivery. For selecting a supply, see the auxiliary circuit current consumption in the
technical data.
WARNING!
Use the LCL filter only with an ACS880-204 IGBT supply module. Use the filter
only with an IGBT supply module of an appropriate frame size.
WARNING!
Do not lengthen the output cables.
