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 24 VDC.
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.

Operator’s obligation to exercise diligence
The operator must ensure that
•the Industrial PC is only used for its intended use (see also
Product Description chapter).
•the Industrial PC is in a sound condition and in working order
during operation.
•the operation manual is in good condition and complete, and
always available for reference at the location of the Industrial PC.
•the Industrial PC is operated, maintained and repaired only by
sufficiently qualified and authorized personnel.
•the personnel is instructed regularly about relevant occupational
safety and environmental protection aspects, and is familiar with
the operating manual and in particular the safety notes contained
herein.
•none of the safety and warning notes attached to the Industrial PC
are removed, and that all notes remain legible.
National regulations
depending on the machine
type
Depending on the type of machine and plant in which the Industrial PC is
being used, there will be national regulations for the control of such
machines and plant that the operator must observe. These regulations
cover, amongst other things, the intervals between inspections of the
controller.
The operator must initiate such inspections in good time.
Warning

Product Description
Appropriate Use
The 6525 Industrial PC is designed for mounting in control cabinets or in
the rear panel of a control or console housing for machine and plant
engineering applications. The heat sink of the IPC is thereby fed to the
outside through a suitable cut-out in the panel of the control cabinet. This
ensures that the power dissipation of the processor and chipset is given off
directly to the surroundings.
View form the top
Configuration
The 6525 is a fanless Industrial PC with passive cooling and can hence be
constructed completely without rotating parts. Integrated seals provide for
an IP 67 closure.
Access to the Hard Disk, the CF-Slot and
the Battery
A 2½-inch SATA hard disk (optional), the CF-slot and the battery are
located behind the cover plate on top of the Industrial PC.
Removing the cover plate
After loosening the two screws (1) and (2) the cover plate can be removed.

Installation Instructions
Please also refer to chapter General Notes.
Transport and Unpacking
The specified storage conditions must be observed (see chapter Technical
data).
Transport
Despite the robust design of the unit, the components are sensitive to
strong vibrations and impacts. During transport, your Industrial PC should
therefore be protected from excessive mechanical stress. Therefore,
please use the original packaging.
Warning
Danger of damage to the unit!
If the device is transported in cold weather or is exposed to extreme
variations in temperature, make sure that moisture (condensation) does not
form on or inside the device.
Prior to operation, the unit must be allowed to slowly adjust to room
temperature. Should condensation occur, a delay time of approximately 12
hours must be allowed before the unit is switched on.
Unpacking
Proceed as follows to unpack the unit:
1.Remove packaging.
2.Do not discard the original packaging. Keep it for future relocation.
