3.3.1 SK CU4-… optional modules
As so-called internal control terminals, SK CU4- optional modules enable the scope of functions of the
FIs to be extended without changing the size. The FI provides two slots for installation of the
corresponding modules. These modules are selected in the order as part of the configuration process
for the FI. Retrofitting is not possible.
The following combinations are possible.

This option module requires both installation slots and therefore cannot be combined with other
optional modules.
