2.3 NORDAC SK 750E and trio SK 300E
By the use different modules for display, control and parameterisation, the NORDAC SK 750E and trio
SK 300E can be easily adapted to various requirements.
Alphanumerical display and operating modules can be used for simple commissioning. For more complex
tasks, various connections to a PC or an automation system can be selected.
The technology unit (Technology Unit, SK TU2-…) is connected externally to the front of the frequency
inverter and is therefore easy to access and replace at any time.
In addition, further modules (customer interfaces and special extensions) can be used in the frequency inverter
for the processing of digital and analogue signals, and with the SK 750E, for speed control or positioning.
WARNING
NOTE
Modules should not be inserted or removed unless the device is free of voltage. The slots may
only be used for the intended modules.
Installation of a technology unit separate from the frequency inverter is not possible. It must be
connected directly to the frequency inverter.
Operation is not permitted if there is no secure PE connection to the frequency inverter and to
the technology unit!
