Operating Instructions 
 
Please also refer to chapter General instructions. 
 
 
Switching the Industrial PC on and off 
Switch on 
The Industrial PC does not have its own mains switch. The Industrial PC 
will start when the equipment is switched on, or when it is connected to the 
power supply. 
 
Shutting down and 
switching off 
When the plant is switched off, or when it is disconnected from its power 
supply, the Industrial PC will be switched off. 
 
Control software such as is typically used on Industrial PCs permits various 
users to be given different rights. A user who may not close software may 
also not switch the Industrial PC off, since data can be lost from the hard 
disk by switching off while software is running. 
 
 
 Warning 
First shut down, then switch off the PC! 
If the Industrial PC is switched off as the software is writing a file to the 
hard disk, the file will be destroyed. Control software typically writes 
something to the hard disk every few seconds, so that the probability of 
causing damage by switching off while the software is running is very high. 
 
 Warning 
When you have shut down the Industrial PC, you have to switch off power 
supply for at least 10 seconds before rebooting the system. 
After resetting power supply the PC will start booting automatically. 
 
Reset key 
A Reset button for rebooting the system is 
provided on the front cover. 
LEDs 
Three LEDs are located next to the Reset button. 
The red LED signalises hard disk activity, the green LED signalises the 
presence of the voltage supply, while the yellow LED indicates Turbo 
operation. 
 
First switching on and driver installation 
 
When you switch on the Industrial PC for the first time, the pre-installed 
operating system (optional) will be started. In this case, all the required 
drivers for any additional, optional hardware components ordered with the 
PC will already have been installed. 
 
If the PC was ordered without operating system, you have to install the 
operating system and the driver software for any auxiliary hardware 
yourself. Please follow the instructions in the documentation for the 
operating system and the additional devices.
