Option modules
Option modules are used to extend the functionality of the device.
These options are available as an installation variant, the so-called SK CU4-… customer unit, and also
as an attachment variant, the so-called SK TU4-… technology unit. As well as the mechanical
differences, the installation and attachment variants also have some functional differences.

Attachment variant
The external technology unit (Technology Unit SK TU4-…) is externally attached to the device and
is therefore easy to access.
A technology unit basically requires the use of a suitable SK TI4-TU-… connection unit.
The power supply and signal lines are connected using the screw clamps of the connection unit.
Depending on the version, additional connections for connectors (e.g. M12 or RJ45) may be available.
The optional wall mounting kit SK TIE4-WMK-TU also allows the technology units to be mounted away
from the starter.
Built-
in variant
The internal customer unit (Customer Unit, SK CU4-...) is integrated in the device. The power
supply and signal lines are connected using screw clamps.
