3.1.2 Overview of external technology units SK TU4-…
External technology units enable the modular extension of the scope of SK 2xxE frequency inverter
functions.
Users have access to both communication modules and an internal mains unit or an I/O expansion and
other modules.
Bus modules with connection terminals or M12 system connectors are available as options.
Modules with protection class IP55 or optionally IP66 can be ordered according to the installation location.
These can be mounted directly on the SK 2xxE or separate from the SK 2xxE by means of a suitable wall-
mounting kit.

available for bus modules or the I/O extension. The mains unit or potentiometer modules require an
SK TI4-TU-NET Connection Unit. The SK TI4-TU-MSW must be used for the maintenance switch.
For the bus modules or I/O extension with integrated system bus an RJ12 socket (behind a transparent
screw-on cover) is also available. This enables communication with other modules or frequency inverters.
With this linkage, all devices can be parameterised by means of a ParameterBox SK PAR-3H or with a PC
and the NORD CON software.
The bus modules require an external 24V supply, and are therefore also ready for operation if the frequency
inverter is not connected to the mains supply.
