3.4 Details of external Technology Units SK TU4-
…
The technology units are divided into two different groups. The BUS group contains all the bus modules and
the I/O extension. These are connected to the SK 1x0E via the system bus.
The second group includes other technology units, e.g. the maintenance switch SK TU4-MSW.
Due to the very different functions, the device groups require different connection units.

All connections are made via the connection unit. This includes customer control of the
module and connection of the module to the frequency inverter. In parallel with this, the
analog and digital inputs and outputs of the frequency inverter also remain available.
The relevant Technology Unit is attached to the appropriate Adapter Unit with screws.
Installation information can be found in Section 3.2.2.
NOTE
Connection terminals with identical designations are first connected internally, if the
technology unit has been mounted on the corresponding connection unit. Because of this,
when removing a BUS module from the connection unit, the relevant BUS system (e.g.
Profibus) is disconnected.
