3.2 Overview of Technology Units
Technology units are optional modules and are plugged onto the top of the frequency inverter. They are for the
control or parameterisation of the inverter and for the display of the actual operating values. The
PotentiometerBox and the ControlBox are available as technology units for simple control of the frequency
inverter and various bus modules are available for connection to a higher level control unit.
A differentiation is made between IP55 and IP66 technology units. Technology units with protection class
IP555 are used for the air cooled SK 750E and protection class IP66 is used for the water cooled SK 750E.

hen inserting the technology units, the left and right slots must be considered separately. The
left hand slot must only be used for the ControlBox or PotentiometerBox control unit. The right
hand slot can be used for all modules. Combined operation of the PotentiometerBox and the
ControlBox is not possible!
ATTENTION The technology units SK TU2- … are available for protection class IP55 and technology units
SK TU2- …-C for IP66. It must be noted that the functionality and dimensions of the technology
units are identical for the IP55 and IP66 versions. However, with the IP66 version special
measures, such as coated PCBs are used in order to comply with the protection class.
