	Can the DE4-CFG-200 configuration software be ordered separately?
	The DE4-CFG-200 configuration software cannot be ordered separately. It is part of the documentation (AWB823-1279-D/GB/F) of the DE4-COM-2X serial interface and is supplied on CD.

	Is it possible to use the DE4-NET-K network module with DF4-120 frequency inverters ?
	The DE4-NET-K network module cannot be used with DF4-120 frequency inverters. The module is used to connect the DF4-340 and DF4-341 frequency inverters directly to the Suconet K fieldbus.

	When should motor chokes be used ?
	When long motor feeders are involved. These are used to reduce the edge steepness of the inverter output voltage.

	Should a mains choke always be used ?
	It is recommended. With some frequency inverters this is absolutely necessary.

	When are radio suppression filters used?

	What should be taken into account with the cyclical mains switching of frequency inverters ?
	Frequency inverters should be switched on at most once every 3 minutes otherwise the internal inrush current limit will be exceeded.

	When should sinusoidal filters be used?
	When the frequency inverter is to supply a sinusoidal output voltage. With long motor feeders. To reduce the edge steepness of the inverter output voltage.

	Can DF5 and DV5 series frequency inverters be connected to PROFIBUS-DP?
	Yes

	Which electric circuit should be used for the DF5 and DV5 frequency inverter in order to directly connect the negative logic of the frequency inverter to the positive logic of the PLC ?
