2. Product overview
Intended use
The CX5010 / CX5020 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. 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! Replacing control components while the
system is live may lead to short circuits or overvoltages, which in turn may damage the
controller and connected 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
Requires software knowledge! Each user must be familiar with all the functions of the
software installed on the PC to which he has access.
