4 Intended use
NOTICE Risk of damaging the device if not expressly stated accessories,
mounting parts and other components, cables, lines, software
and firmware are used.
The ctrlX CORE control may only be used with the accessories
and mounting parts listed in this documentation. Components
that are not expressly mentioned must neither be attached nor
connected. The same applies to cables and lines.
Only to be operated with the component configurations and com-
binations expressly defined and with the software and firmware
specified in the corresponding functional description.
Typical areas of application of the control:
•Handling and assembly systems
•Packaging and food processing machines
•Printing and paper converting machines
•Machine tools
•Wood working machines
•General mechanical engineering
•Building automation
The ctrlX CORE control may only be operated under the mounting and installation conditions, in the
position of application and under the ambient conditions (temperature, degree of protection, humidity,
EMC, etc.) specified in this documentation.

10.2 Installation notes
NOTICE Destruction of the device due to electrostatic discharge
The device contains components that can be damaged or
destroyed by electrostatic discharge. Comply with the required
safety measures against electrostatic discharge (ESD) acc. to EN
61340-5-1 when operating the control.
•Mounting location
The control has the degree of protection IP20 and is thus intended for the use in a closed control
cabinet or control box (terminal box) of the degree of protection IP54 or higher.
•Mounting rail
Mount the control on a 35 mm standard mounting rail. Only use a mounting rail with an design
height of 7.5 mm (corresponds to TH 35-7.5 acc. to EN 60715).
The fastening distance of the mounting rails may not exceed 200 mm. This distance is required to
ensure stability while mounting and dismounting the control.

•Mounting position
To ensure air cooling in the device by convection, mount the control only vertically as shown in the
following figure.
In the shown mounting position, the natural convection supports the forced cooling air flow. Heat
pockets can thus not be caused in the device.

•End clamps
Fasten end clamps on both sides of the control.
End clamps ensure the correct fastening of the control connected to them on the mounting rail and
they are used as lateral end elements.
Always fasten the left end clamp of the station before mounting the control. This ensures the fol-
lowing:
–It impedes the shifting of the control.
–The installation place for the end clamps is secured.
•Do not route cables parallel to motor cables or other strong interference sources to avoid the cou-
pling of interferences.

•The cabling of the Ethernet wires may not leave the building.
•Observe the bending radius of the cables used when routing the connecting lines.
•Use strain reliefs for all cables.
•Install the control only horizontally on a mounting rail attached to a wall.
•Keep the maximum distance possible from interference sources.
•Provide the following minimum distances for sufficient cooling:
In case of a several line design, the supply air has to be measured under each line and its limit value
has to be observed. For information on ambient temperatures, refer to⮫ Chapter 6 Ambient condi-
tions on page 11

•Additionally, provide sufficient distance for mounting, dismounting, plugs and cables.
10.3 Mounting the control
NOTICE Damage of the device by plug mounting under voltage!
−Before mounting or dismounting components, disconnect
the control - including its components - from voltage.
−Connect the voltage only after the control and its compo-
nents have been set up.
