3.2 Interface description
The CP6606 has the following interfaces:
• Power supply (X101)
• Ethernet RJ45 (X102)
• EtherCAT (X103)
• USB (X104, X105)
• RS232 (X107)
3.2.1 Power supply
The Panel PC is supplied with a nominal voltage of 24V. The power supply and the protective earth of the
PC are connected via the five-pin voltage socket (X101). The main supply voltage is applied between PIN 4
(0V) and PIN 5 (24V) of the socket. If the Panel PC is equipped with an internal, capacitive 1-second UPS
(uninterruptible power supply), this is also supplied via the voltage. The 1-second UPS does not serve to
back-up the operating system.

Operation of the Panel PC
The Panel PC is operated via the touch screen.
NOTE
Damage to the touch screen
Operating the touch screen with unsuitable objects may damage the touch screen.
• Only operate the touch screen with your bare finger or with your finger using a suitable glove.
• If you use gloves, make sure that no hard particles such as metal shavings, glass splinters or similar ad-
here to the glove.
Commissioning
In order to use the Panel PC, you must first commission it. The first step is to transport the device to is
operating location and unpack it. This is followed by installing the device in the panel of the control cabinet,
connecting the cables and the power supply and finally switching on the Panel PC.
4.1 Transport and storage
The specified storage conditions must be adhered to (see chapter 8 Technical data [}34]).
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts. During
transport the device must therefore be protected from mechanical stress. Appropriate packaging of the Panel
PC, in particular the original packaging, can improve the vibration resistance during transport.
NOTE
Hardware damage due to condensation
Unfavorable weather conditions during transport can cause damage to the device.
• Protect the device against moisture (condensation) during transport in cold weather or in case of ex-
treme temperature fluctuations.
• Do not put the device into operation until it has slowly adjusted to the room temperature.
• Should condensation occur, wait for about 12 hours before switching the device on.
Unpacking
Proceed as follows to unpack the device:
1. Check the packaging for transport damage.
2. Remove packaging.
3. Keep the packaging for possible future transport.
4. Check your delivery for completeness by comparing it with your order.
5. Check the contents for visible shipping damage.
6. In case of discrepancies between the package contents and the order, or in case of transport damage,
please inform Beckhoff Service (see Chapter 9.1 Service and Support [}35]).
4.2 Control cabinet installation
The Panel PC CP6606 is designed for installation in the front of a control cabinet in machine and system
engineering. The environmental conditions specified for operation must be observed (see chapter 8
Technical data [}34]).

Commissioning
CP660618 Version: 2.0
4.2.1 Dimensions
The dimensions of the Panel PC are required for the preparation of the control cabinet front. For the
installation of the Panel PC, the wall thickness must be between 1 mm and 5 mm. After installation, be sure
to check the tightness between the Panel PC and the built-in wall.
All dimensions are in mm.

4.2.2 Installation in the control cabinet
The control cabinet must have the required installation cutout according to the device dimensions (see
Chapter 4.2.1 Dimensions [}18]) of the Panel PC.
NOTE
Extreme environmental conditions
Extreme environmental conditions can cause damage to the device.
• Avoid extreme environmental conditions.
• Protect the device against dust, moisture and heat.
• Do not block the ventilation slots of the device.
Please also note the following for installation in a control cabinet:
• For air circulation, ensure that there is 5 cm of free space above and below the device.
• Position the Panel PC such that reflections from light sources on the screen are avoided as far as
possible.
• For the correct installation height, use the position of the screen for guidance. This should always be
optimally visible to the user.
• Do not expose the Panel PC to direct sunlight.
Installation in the control cabinet
Once you have made the required cutout in the control cabinet, you can install the Panel PC in the control
cabinet. Clamping levers are provided at the back of the housing for final mounting of the device.
To install and secure the Panel PC in the control cabinet, follow the steps shown in Fig. 11:
1. Insert the Panel PC at the intended position in the panel of the control cabinet. Make sure that the device
is secured against falling out until it is fastened properly.
2. Loosen the clamping levers with a 2.5 mm Allen key (sections A and B).
3. Fold out the clamping levers 90° (section C).
4. Retighten the clamping levers with the Allen key (section D).

4.2.3 Wall installation with wall mounting frame
NOTE
Reduced operating temperature range
Installing the CP6606 in the wall mounting frame reduces the operating temperature range to a maximum of
45°C.
• Ensure that the maximum operating temperature range of the Panel PC is not exceeded.
As an alternative to installation in the front of a control cabinet, you can install the Panel PC in a wall recess.
For this you need a wall mounting frame. Use the following Beckhoff option:
• C9900-M317: wall mounting frame for building installation for 7-inch "Economy" built-in Panel PC
CP6606
Observe the following aspects when installing in the wall:
• The required wall cutout is 198 x 202 mm (W x H).
• Observe the correct installation position (top/bottom) of the wall mounting frame. The cable chamber is
located underneath the device (see Fig. ?).
• The installation frame must not protrude beyond the wall plaster and must be no more than 5 mm
deeper.
• You must mount the mounting frame horizontally. You cannot subsequently align the Panel PC in the
mounting frame.
• The maximum projection of the screw heads on the inside of the mounting frame must not exceed
2.5mm.
To install the Panel PC in a wall using the wall mounting frame, follow the steps below shown in Figure 12:
1. Screw the enclosed latching elements of the ball catch onto the back of the Panel PC using the M3x6
screws (section A).
2. Install the wall mounting frame flush in the intended wall (section B).
3. If necessary, adjust the position of the mounting frame in the wall using the ball catches.
4. Screw the wall mounting frame into the wall using the four ST 3.5 x 25 screws (section C).
5. Snap the Panel PC into the ball catches of the wall mounting frame.
6. Plaster the lower part of the wall mounting frame flush with the surface (section D).
ðYou have installed the Panel PC in a wall.
