Switching on and off
Switching on
The power supply for the basic CPU module and the extension module comes from the power supply unit. When the power supply unit is connected to the electricity supply, the basic CPU module and the extension module start automatically.
Further information on how to connect the power supply unit to the electricity supply can be found in the following documentation:

Switching on for the first time
When you switch on the PC for the first time, the pre-installed operating system (optional) will be started.
Switching off
The control software typically running on Embedded PCs should be shut down or stopped correctly. A user who is not allowed to terminate the software is also not allowed to switch off the Embedded PC. Switching off while the software is running may lead to loss of data from the hard disk.
Once the software has been stopped, the operating system can be shut down. Only then should the power supply be interrupted. If the electricity supply for the power supply unit is switched off, the basic CPU module and the extension module are also switched off.
