Technical Information / Datasheet
Scope of supply
Field of use
External IO extension for mounting on, or in the immediate vicinity of a decentralised frequency
inverter (SK 2xxE). This can be connected to the inverter via the system bus. Four digital inputs, 2
digital outputs, 2 analog inputs and 1 analog output are available.

Installation location
on the left or right on the connection unit of the frequency inverter,
alternatively: near to the inverter by means of the SK TIE4-WMK-TU wall-mounting
kit
Fastening
With screw fasteners
NOTICE
Sealing
When installing (module, cable glands, plug connectors), take care that there is a good seal, in order to prevent
the entry of moisture and the danger of corrosion and short circuits. With IP66 modules (SK TI4-TU-...-C) the
membrane valve (supplied) must be screwed in, in order to prevent the accumulation of condensation.
1.
Switch off the mains.
2.
Remove the two M25 caps on the required side of the frequency
inverter (right / left).
3.
Remove the printed circuit board (with terminal bar) from the
SK TI4-TU-…. connection unit.
4.
Install the SK TI4-TU- ... with the enclosed seal on the SK 2xxE
using the 4 enclosed bolts.
5.
Insert both of the enclosed grommets in the M25 cable glands (to
protect the internal wiring between the module and the frequency
inverter).
6.
Replace the printed circuit board (See point 3) and carry out the
electrical connections.
SK TI4-TU-…-C version devices: remove the top M20 cable gland
(however not at the diagnostic inlet) and insert the enclosed
membrane valve into this screw fitting.
7.
Fit and screw on the SK TU4 module.

2 TI 275281106 - 4912
IO-Extension – SK TU4-IOE
1.
Switch off the mains.
2.
Attach the enclosed seal to the SK TI4-TU ... and place it on the
wall-mounting kit. Tightly screw the 2 oval-head screws (enclosed
with the wall-mounting kit) into the (countersunk) holes in the wallmounting kit from the outside.
3.
Insert and tighten the 2 bolts (enclosed with the wall-mounting kit)
from the inside into the freely accessible holes in the rear wall.
4.
Install the unit at the installation site and make the electrical
connections (maximum cable length 20m)
5.
Fit and screw on the SK TU4 module.
Information
Contacts
The connection between the module and the connection unit is made by means of a pin connector. Terminals in
the terminal bar of the connection unit with an identical potential are connected by fitting the module and
connection unit together.
1.
No function, M20 x 1.5
2.
Diagnostic access, RJ12 socket
3.
M20 x 1.5 cable gland (1 on the left and 1 on the right):
incoming or outgoing cable, e.g. for system bus or 24V supply
4.
M25 x 1.5 cable gland (2x):
For wiring between the optional module and the frequency inverter
in case of direct attachment.
5.
M16x1.5 cable gland (4x):
