Appropriate Use
The CX1020 device series is a modular control system designed for top-hat 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. Disconnect the device by pulling the first terminal after the power supply unit
(CX1100-002 and CX1100-002) (optional) and the fieldbus connectors.
System components that have been switched off must be secured against being switched on again.
The power supply unit of the Embedded PC requires a 24 V DC supply.
Danger
Do not exchange any parts when under power!
When components are being fitted or removed, the supply voltage must be switched off.
