Modular options

By combining different modules for display, control and parameterisation, the NORDAC 300E can be easily
adapted to various demands.
Modules are available for processing analogue and digital signals as well as all common fieldbus systems.
Alphanumerical display and operating modules can be used for simple start-up. For more complex tasks,
various connections to a PC or an automation system can be selected.

Technology units (Technology Unit, SK TU2-…, SK TU2-…-C)

are located on top of the frequency inverter

and are accessible from the outside - they are used for manual control or parameterisation, or they can provide
connection to fieldbus systems.

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, special measures (see Chap. 1.7)
are implemented in the IP66 version to maintain this protection class.

Customer units (Customer Unit, SK CU2-…, SK CU2-…-C)

are installed inside the frequency inverter.

They enable control with digital and analogue signals.

ATTENTION

The customer units SK CU2-… are available for protection class IP55 and customer units
SK CU2-…-C

for IP66. It must be noted that the functionality and dimensions of the customer

units are identical for the IP55 and IP66 versions. However, special measures (see Chap. 1.7)
are implemented in the IP66 version to maintain this protection class.

WARNING

Modules should not be inserted or removed unless the device is free of voltage. The slots may
only be used for the applicable modules.
Installation of a technology unit separate from the frequency inverter is not possible. It must be
connected directly to the frequency inverter.
