Basic security measures
Before the Touch PC may be switched off, the running software must be closed as usual. Otherwise
data on the hard disk may be lost. Please read the section Switching the Touch PC on and off.
Attention
Switch off all system components, then disconnect the fieldbus
Before opening the Touch PC housing and whenever the Touch PC is not
used for control purposes, for example during the functional test after a
repair, all system parts must first be switched off and then the Touch PC
must be disconnected from the system.
Switched off system parts must be secured against being switched on
again.
Attention
Do not replace any parts when under voltage
When installing and removing components, the supply voltage must be
switched off.
Damage can occur during installation in the Touch PC:
• If metal objects such as screws or tools are placed in
the circuit boards.
• If PC internal connection cables are pulled off
or plugged in during operation.
• If plug-in cards are removed or inserted when the PC is
switched on.
