2 Assembly and installation
2.1 Installation and assembly
Only external technology units (Technology Units) are available for PROFINET IO. These are tailored to the
NORD SK 200E frequency inverter series.
These are used to connect SK 200E series speed regulated drive units to overriding automation systems via
the PROFINET IO field bus.
SK 200E with external technology unit SK TU4- …
and BUS connection module SK TI4-TU-BUS
SK TIE4-WMK-TU with BUS connection module SK TI4-TU-BUS
and external technology unit SK TU4-PNT
The technology units (Technology Unit, SK TU4-...) are externally attached to the SK 200E 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. The electrical connection to the SK 200E is made via the
internal system bus. Optionally, 4 or 5 pin M12 round connectors are available (for installation on the BUS
connection unit SK TI4-TU-BUS), which can be used for connection of the digital I/Os and the system bus
cables.
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-...) cannot be operated without the BUS connection unit
(SK TI4-TU-BUS)!
NOTE
Only one technology unit (SK CU4-... or SK TU4-...) can be connected to a system bus.
