Danger
i
Note
Before the Built-in Panel 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 Switching the Built-in Panel PC on and off.
Before opening the housing, and whenever the Built-in Panel PC is
not being used for control purposes (such as during functional
checks after a repair), all parts of the equipment must first be
switched off, after which the Built-in Panel PC is to be disconnected
from the equipment.
Disconnect the device by unplugging the connectors on the rear side of the
Built-in Panel PC.
Items of equipment that have been switched off must be secured
against being switched on again.
Displays used for the Built-in Panel PC’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
Built-in Panel PC is opened!
Assembly work on the Built-in Panel PC during operation may damage the
device:
• if metal objects such as screws or tools fall onto operating circuit
boards.
• if connecting cables internal to the Built-in Panel PC are removed
or inserted during operation.

Installation Instructions
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.
Danger of damage to the unit!
Warning
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 PC in the control cabinet
The Built-in Panel PC CP67xx is designed for mounting in control cabinets
in machine and plant engineering applications.
The ambient conditions specified for operation must be observed (see the
section on Technical data).
Preparation of the control
cabinet
i
Note
Warning
Installation in a control
cabinet wall
The control cabinet wall must be prepared with the required mounting
opening for the computer unit according to the Built-in Panel PC’s
dimensions.
When the unit is installed in an enclosure, adequate space for
ventilation must be provided.
Please note the following points during installation of the Built-in Panel PC:
• Position the Panel 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 Panel PC should not be exposed to direct sunlight.
• When the unit is in its mounting position, the ventilation openings must
not be obstructed.
Extreme environmental conditions should be avoided as far as
possible. Protect the rear of your PC from dust, humidity and heat.
Proceed as follows:
1. Insert the Built-in Panel PC at the intended control cabinet wall position
and protect it from falling out, prior to final mounting.
2. Release the clamping levers with a No. 3 Allen key, turn the clamping
levers to the side through 90° and retighten the screws.

Please read the documentation for the external devices prior to connecting
them.
During thunderstorms, plug connector must neither be inserted nor
removed.
When disconnecting a plug connector, always handle it at the plug. Do not
pull the cable!
Connecting cables
The connections are located at the rear of the Built-in Panel PC and are
documented in the Product Description section.
When connecting cables to the Panel PC, please adhere to the following
order:
• Disconnect the Panel PC from the power supply.
• Connect all cables at the Panel PC and at the devices to be
connected.
• Ensure that all screw connections between connectors and
sockets are tight!
• Reconnect all devices to the power supply.

Switching the Built-in Panel PC on and off
Switch on
Shutting down and
switching off
The Built-in Panel PC does not have its own mains power switch. As soon
as the power supply is switched on the Panel PC is activated.
Control software, as typically applied in Industrial PCs, enables the
assignment of different rights to all users. A user who is not entitled to shut
down the software may not switch off the Built-in Panel PC as an attempt
to shut it down when the software is running could result in the loss of
software data on the Compact Flash memory card (CF card).
First shut down, then switch off the Panel PC!

i
Note
Type-dependent number of

Operation
Hom e En d
Pg Up Pg Dn
If the Built-in Panel PC is shut down while the software is writing a file onto
the CF Card memory card, the file will be destroyed. Control software
typically writes something to the CF card every few seconds, so that the
probability of causing damage by switching off while the software is running
is very high.
When you have shut down the Panel PC, you have to switch off power
supply for at least 10 seconds before rebooting the system.
After resetting power supply the Panel PC will start booting automatically.
Operation
The Built-in Panel PC’s membrane keypad may only be actuated by
fingertips.
Attempts to actuate it with other objects can easily result in the destruction
of the device. Neither may the membrane keypad be operated with a touch
screen pen.
The touch screen may only be actuated by finger tips or with the touch
screen pen. The operator may wear gloves but there must be no hard
particles such as metal shavings, glass splinters embedded in the glove.
Keyboard codes
Depending on the precise type, the Control Panel can have fewer keys
than those described here.
The cursor is the blinking character that marks the point at which the next
character entered will be displayed. The cursor is also known as the
insertion point. The cursor keys each move the cursor one place in the
associated direction.
The Home key moves the cursor to the beginning of the line, while the End
key moves it to the end of the line.
The Pg Up key scrolls one page back, the Pg Dn key scrolls one page
forward.
The Tab key takes the cursor to the next input field, while Shift and Tab
moves to the previous input field.

right hand keys of a Microsoft mouse.
The Del key deletes the character to the right of the cursor.
The Ins key causes characters to the right of the cursor to be overwritten.
The overwrite mode is cancelled by pressing the key again.
Print-Screen prints a hard copy of a text screen on the printer.
The Pause key stops the computer until another key is pressed (only under
MS-DOS).
Your input is confirmed with the Enter key.
Backspace deletes the character to the left of the cursor.

Pressing the Shift key cancels this function.
Rather like the effect of the Shift key, Ctrl and Alt also change the meaning
of another key that is pressed at the same time.

Pressing this key opens the property sheet of the active (or marked) object.
