Technology Units (TU) are modules that can be inserted from above
for display, parameterisation and control of the inverter.
2 Option modules for SK 300E, SK 5xxE, SK 700E and SK 750E
2.1 Bus modules for the SK 700E and SK 5xxE
Technology units, customer units and special extension units
Through the combination of modules for the display, technology units and modules with digital and analog inputs,
as well as interfaces, customer units or special extension units, the NORDAC SK 700E can be easily adapted
to the requirements of various applications.
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. The slots are coded to prevent them being
mixed up.
Extension Units (XU) are inserted into the slot at the base of the
inverter. Such an extension unit is required if the speed is to be
controlled or positioned by an incremental (absolute) encoder.
Customer Units (CU) are modules inserted inside the inverter in the
upper recess. They are used for control and communication using
digital/analog signals or bus interfaces.
