2 Product overview
2.1 Intended use
The CX20x0 device series is a modular control system designed for top­hat rail installation. The system is
scalable, so that the required modules can be assembled and installed in the control cabinet or terminal box
as required.
Only switch the PC off after closing the software
Before the Embedded PC is switched off, the software currently running on it should be stopped properly in
order to avoid data loss on the hard disk. Please read the section on “Switching off”.
Switch off all system components and uncouple the Industrial PC from the system if the PC is not used for
control purposes, e.g. during a function test. To disconnect first pull the first terminal behind the power
supply unit (optional), then pull the connectors of the fieldbus connections.
System components that have been switched off must be secured against being switched on again.
The Embedded PC’s power supply unit must be supplied with 24 V
DC
.
Attention
Damage to the environment or devices
Do not exchange any parts when under power! The exchange of controller parts when live
can lead to short­circuits or overvoltages. These can damage the controller itself and con­
nected peripherals (terminals, monitors, input devices, etc.).
When components are being fitted or removed, the supply voltage must be switched off.
Software knowledge
Attention
System malfunctions
Mandatory software knowledge! Every user must be familiar with any of the functions of the
