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 storage medium is lost. Please
read the section Switching the Industrial PC on and off.
Attention
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 24VDC.
CAUTION
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.
Attention
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.
DANGER
High Voltage!
Displays used for the Control Panel’s LC-display are operated with a
voltage of up to 1000 V, depending on type. For that reason:
The supply voltage must be disconnected before the housing of the
Control Panel is opened.

Foreword

Product Description
Appropriate Use
The CP72xx Panel PC with 3½” motherboard is designed for mounting
behind a Beckhoff Control Panel. Cooling is achieved via heat sink
structure between the Control Panel and the add-on PC. A fan inside the
closed housing ensures that the heat is distributed evenly.
The Industrial PC is designed for mounting arm installation.
DANGER
Do not use the Panel PC in areas of explosive hazard!
The Panel PC must not be used where there is a risk of explosion.

Installation Instructions
Please also refer to chapter Foreword.
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 Control Panel should
therefore be protected from excessive mechanical stress. Therefore,
please use the original packaging.
Attention
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.
3. Check the delivery for completeness by comparing it with your order.
4. Please keep the associated paperwork. It contains important
information for handling the unit.
5. Check the contents for visible shipping damage.
6. If you notice any shipping damage or inconsistencies between the
contents and your order, you should notify Beckhoff Service.

Installation Instructions

Installation of the Panel PC
The Panel PC series CP72xx is designed for mounting arm installation. A
Control Panel is installed in the front of the IP65 Panel PC.
The ambient conditions specified for operation must be observed (see the
section Technical data).
Note
Circulation of air
When the unit is installed in an enclosure, adequate space for ventilation
and for opening the PC must be provided.
Please note the following points during installation of the PC:
• Position the PC in such a way that reflections on the screen are
avoided as far as possible.
• Use the position of the screen as a guide for the correct installation
height; it should be optimally visible for the user at all times.
• The PC should not be exposed to direct sunlight.
Attention
Avoid extreme environmental conditions
Extreme environmental conditions should be avoided as far as possible.
Protect the rear of your PC from dust, humidity and heat.
The clearance above and below the housing must be at least 20 cm in
order to ensure adequate ventilation of the PC.
The cooling ribs of the PC must not be covered.
Mounting arm installation

Beckhoff power supply technology
Schematic diagram of
power supply unit wirings
Innovative solution for
shutting down Industrial
PCs
Industrial PCs equipped with a UPS are in actual use frequently switched
off by simply turning off the supply voltage. In this case the PC shuts down
via the battery. However, over time this reduces the service life of the
battery.
The new Beckhoff power supply technology approach addresses this
problem and now offers the user the option of switching the PC off without
the need for using the battery, thereby reducing the load on the battery.
In addition to the main switch this innovative solution uses an ON/OFF
switch for the machine. Basically, the main switch remains switched on and
provides the power supply for the PC during shutdown.
Once the PC has shut down, the PC power supply unit issues a signal to
indicate that the process is complete and that the main voltage can be
switched off. This can be done manually via a signal lamp connection or
via a contactor. With this solution the main switch generally only has to be
switched off if the control cabinet has to be opened.

Installation Instructions
CP72xx 15
In order to maintain a screen display for the Industrial PC in the event of a
power failure, the power supply unit is equipped with a UPS output for
connecting a Control Panel. This enables a power failure to be visualised
and displayed to the user. Once the PC has shut down, the UPS output is
switched off in order to avoid total discharge of the battery.
Note
Internal connection
The UPS output of the CP72xx power supply unit is internally connected
with the panel
For a detailed functional description please refer to section Connecting
Power Supply.

Installation Instructions
CP72xx 17
Connecting Power Supply
The external wiring consists of the connection of the power supply, the
battery pack (optional) and the connection of customised components for
shutting down the PC.
Cable Cross Sections
Note cable cross sections,
avoid voltage drop!
For the connection of the power supply, wiring with a cable-cross-section
of 1.0 mm2 must be used.
With bigger distances between voltage source and PC, you take the
voltage drop as a function of the cable-cross-section as well as voltage
fluctuations of your distribution voltage into account, so that is secured that
the voltage doesn't fall under 22 V at the power supply.
Attention
Insert fuse
The power supply must be protected with maximum 10 A.
Configuration for shutting down the PC
The connections for shutting down the Industrial PCs are established via
the PC_ON input and the Power Status output.
PC_ON and Power Status functions
• If the PC_ON input is connected to 24 V via a switch, the PC shuts
down according to the rules. The PC_ON signal is inverted, i.e. the
PC shuts down if the 24 V connection is live.
• If the PC_ON input is NOT connected by the user, the PC can be
booted in the familiar way by connecting the supply voltage and shut
down via the battery by switching off the supply voltage.
Attention
Service life of the rechargeable battery
This procedure significantly reduces the service life of the rechargeable
battery and should therefore not be used.
• Once the PC has shut down, the Power Status output is switched
from 24 V to 0 V. Via this output a signal lamp can be connected or a
contactor for de-energising the whole system. The maximum load for
the Power Status output is 0.5 A and a suitable fuse should be
provided.
