2.1 Installation and assembly
Internal and external technology modules designed for NORDAC SK 200E series are available for DeviceNet.
Except for the number of digital inputs and outputs, the functionalities of the various DeviceNet modules are
identical.
These are used to connect SK 200E series speed regulated drive units to overriding automation systems via
the DeviceNet field bus. Both the SK 200E frequency inverters and the external technology units are available
in the protection classes IP55 (standard) and IP66 (optional). The type designation of the SK 300E and the
modules in the protection class IP66 is given an additional code "-C" (coated → coated board) to differentiate the
IP55 and IP66 protection classes.

The internal technology modules (Customer Unit, SK CU4-...) – designated as the customer unit – are
integrated into the connection unit of the SK 200E. The electrical connection to the SK 200E 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 200E,
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 200E frequency inverter.
