Transport and unpacking

The specified storage conditions must be adhered to (see chapter 9 Technical data [} 33]).
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
device, such as the original packaging, can improve the vibration resistance during transport.
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
extreme 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 10.1 Service and Support).

Connecting the panel PC

Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never connect or disconnect the device cables during a thunderstorm.
• Provide protective earthing for handling the device.
To make the device ready for operation, you have to connect it. The first step is to ground the device. Then
you can connect the cables and the power supply.
An external power supply unit is required for the power supply, which supplies 24 V DC (-15%/+20%) from
an isolated source. This must be protected by a fuse in accordance with UL 248 with a maximum nominal
value of 4 A.
