Jumpers and terminals on the inverter
If a transformer is installed in a cabinet unit, the transformer connections must be changed to
the correct line voltage.

Motor selection
Three-phase asynchronous motors or three-phase synchronous motors can be used for your
inverter. The use of several motors simultaneously is permitted.
●
The total of the motor outputs must not exceed the inverter output. You may operate
smaller and larger motors in parallel on one inverter.
●
Take into account during the motor dimensioning that additional losses in the motor are
produced by the non-sine shaped motor current.
●
Note that a motor without external ventilation will be cooled less at speeds less than the
rated speed. Therefore, consult the motor manufacturer for the dimensioning of the
motor.
●
When using Siemens motors, refer to the list "UN03/UN04 Drehstrommotoren für
drehzahlverstellbare Antriebe" to find the relevant inverter output.
