General notes
Basic safety measures
Only switch the PC off after
closing the software Before the Industrial PC is switched off, software that is running
must be properly closed. Otherwise it is possible that data on the
hard disk is lost.
Warning
Switch off all parts of the equipment, then uncouple the fieldbus!
Before opening the PC housing, for example to exchange a hard disk, all
system parts must be switched off first and the Industrial PC must then be
uncoupled from the system.
Pulling out the fieldbus connection plug uncouples the PC (optional).
System components that have been switched off must be secured against
being switched on again.
Warning
Do not exchange any parts when under power!
When components are being fitted or removed, the supply voltage must be
switched off.
Fitting work on the Industrial PC can result in damage:
• If metal objects such as screws or tools fall onto operating circuit
boards.
• If connecting cables internal to the PC are removed or inserted
during operation.
• If plug-in cards are removed or inserted when the PC is switched
on.

Note
Hard disks in hard drive caddies can also be exchanged whilst the
Industrial PC is in operation.
