*It is often a simpler and more economic connection solution to select an Eco inverter rating
which is one kW rating larger rather than to fit an output reactor, see section 14 for de-rating
information.
The maximum switching frequency must be limited to 2kHz for iron cored reactors and 4Hz for
ferrite cored reactors.
For multi-motor connection to a single inverter the total motor cable length is the sum of the
individual motor cable lengths.
