Assembly and connecting

40 Embedded PC

Start-up procedure

Switching the PC on and off

Switching on

The power supply for the basic CPU module comes from the power supply unit. The basic CPU module starts

automatically when the power supply unit is connected to the mains.

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 Embedded PC switches off when the power supply unit is switched off. The control software typically running on

Embedded PCs should be shut down or stopped correctly. A user who may not close software may also not switch

the Embedded PC off, since data can be lost from the hard disk by switching off while software is running.

Once the software has been stopped, the operating system can be shut down. Only then should the power supply be

interrupted.
