2.1 Installation and assembly
Internal and external technology modules designed for the SK 2xxE frequency inverter series are available for
PROFIBUS DP. Except for the number of digital inputs and outputs, the functionalities of the various
PROFIBUS modules are identical.
These are used to connect SK 200E series speed regulated drive units to overriding automation systems via
the PROFIBUS DP field bus.

The internal technology modules (Customer Unit, SK CU4-...) – designated as the customer unit – are
integrated into the connection unit of the SK 2xxE. Electrical connection to the SK 2xxE is made via the
internal system bus. The connection to external peripheral devices is made via screw terminals. The use of the
optionally available 4 or 5 pin M12 round plug connector, installed in the connection unit of the SK 2xxE,
provides a possible interface for connection to the field bus. A maximum of one customer interface (including
any 24V module) can be installed in the SK 2xxE frequency inverter.
