Common motor terminal cubicle

Instead of direct cabling from each inverter module to the motor, it is also possible to
build a common motor terminal cubicle.
WARNING! If a common motor terminal cubicle is constructed, the inverter modules
must be equipped with the +E205 option (internal du/dt filters).
Note that the distance from both modules to the common output should be of roughly
equal length.
