i
Note
This symbol indicates information that contributes to better understanding.
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. Please read the
section on Switching the Industrial PC on and off.
Warning
Switch off all parts of the equipment, then uncouple the fieldbus!
Before opening the housing of the PC, and whenever the PC is being used
for purposes other than plant control, such as during functional tests
following repair, all parts of the equipment must first be switched off, after
which the Industrial PC can be uncoupled from the plant.
Pulling out the fieldbus connection plug uncouples the PC (optional).
Items of equipment that have been switched off must be secured against
being switched on again.
The Industrial PC’s power supply unit must be supplied with 100-240 VAC
or 24 V
DC
(optional).
Danger
Do not open the power supply unit while voltage is applied!
The supply voltage must be switched off before the power supply unit
housing is opened.
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.

Structure
Front view of the C6250
(Similar photograph)
Opening the housing
To open the PC housing, initially rotate the two fast closing screws (see
photograph above) by 90 degrees in either direction using a screwdriver.
The inner chassis can now be pulled out on telescopic guide supports (see
photograph below).
Removable
inner chassis
Undo the two screws (1) of the upper housing cover (2). The upper housing
cover can now be tilted upwards (see photograph below), thus providing
access to the disk drive, the 3 ½ inch hard disk, the processor, the memory
and the plug-in cards.
