PROFIBUS DP – Supplementary manualfor NORD Frequency Inverter SK 2xxE
14 Subject to technical amendments BU 0220 GB-0912
The external technology modules (Technology Unit, SK TU4-...) – designated as the technology unit – are
externally attached to the SK 2xxE connection unit and are therefore easy to access. Mounting of the SK TU4-...
separate from the frequency inverter is possible by means of the wall mounting kit SK TIE4-WMK-TU.
Electrical connection to the SK 2xxE is made via the internal system bus. 4 or 5 pin M12 round plug
connectors (for installation in the BUS connection unit SK TI4-TU-BUS) are available as an option for
connection of the field bus cable. The external modules are also available as a version with integrated M12
round plug connectors (SK TU4-xxx-M12). These enable the connection of up to 4 digital inputs and 2 digital
outputs.
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.
Mounting of the external technology unit remote from the frequency inverter is possible with the
additional wall-mounting kit (SK TIE4-WMK-TU). However, a maximum cable length of 30m
should not be exceeded.
The external technology units (SK TU4-...(-M12) cannot be operated without the BUS
connection unit (SK T14-TU-BUS)!
NOTE
Only one field bus module (e.g. SK CU4-PBR or. SK TU4-PBR) can be connected to a
single system bus.
