3.1 Overview of optional modules
3.1.1 Overview of internal customer units SK CU4-…
Internal customer interfaces enable the expansion of the range of functions of the frequency inverter without
changing its physical size. For example, either a field bus module or an I/O extension can be selected.
The frequency inverter provides one slot for the fitting of an appropriate option. External options (technology
units) are available for additionally required optional modules (Section 3.2.2).
The bus modules require an external 24 V supply. Therefore they are also available if the frequency inverter
is not supplied from the mains, but the 24 V supply to the module is active.

NOTE
The Ethernet module (PROFINET IO, EtherCat, POWERLINK and EtherNet/IP) causes a
derating of the frequency inverter. For detailed information please refer to the data sheet
(TI ...) for the relevant module.
