After you have drilled the holes for the fastening screws in the control cabinet, you can mount the Industrial PC in the control cabinet with the mounting plates. If your device is equipped with additional plug-in card slots, the device and thus the mounting plates are wider. However, the mounting procedure is the same. C6920 Version: 3.2...
1. Place the fastening screws in the drill holes in the rear panel of the control cabinet. 2. Hang the PC on the screws at the marked places on the mounting plate (see fig. 16). 3. Tighten the fastening screws. ð You have successfully installed the Industrial PC in the control cabinet. Version: 3.2 C6920...
Wire the Industrial PC in the control cabinet in accordance with the EN 60204-1:2006 standard on Protective Extra Low Voltage (PELV) so that one side of the circuit or a point on the power source of this circuit is connected to the protective conductor system. C6920 Version: 3.2...

The functional earth is necessary for the EMC of the device. The functional earth is established by connecting the grounding point on the PC mounting plate to the central grounding point of the control cabinet in which the PC is installed. C6920 Version: 3.2...
If you ordered your device with an integrated UPS, then you can connect an external battery pack and install it on a DIN rail near to the PC. Use only Beckhoff battery packs for this: • C9900-U330: Universal battery pack for PCs and Panel PCs in any configuration When using the C9900-U330 battery pack, you can use the UPS output of the power supply unit (UPS Output).
UPS output and the negative pole of the battery pack. The maximum load is 1.4 A (max. 2.5 A from year of manufacture 2016). Once the PC has been de-energized via the UPS software, the UPS output is switched to 0 V. A connected panel is switched off. C6920 Version: 3.2...
• Avoid switching off the power supply before shutting down the operating system. • Use the Beckhoff concept (see below) to shut down the operating system in a battery-friendly manner. When the system is switched off or disconnected from its own power supply, the Industrial PC is also switched off.
Call up the help files either directly from the configuration tab by clicking the Help button or start the file under Start > Programs > Beckhoff > UPS software components. The method of communication between your PC and the UPS depends on the PC generation. The following table provides information about the method of communication according to the device generation: Table 13: UPS communication...
• User name: Administrator • Password: 1 You also have the option of using the Beckhoff Device Manager to remotely configure the Industrial PC via a web browser. More detailed information is available in the Beckhoff Device Manager manual. First start Beckhoff Device Manager When your Industrial PC is booted for the first time, the Beckhoff Device Manager also starts automatically for the first time.
Secure passwords Strong passwords are an important prerequisite for a secure system. Beckhoff supplies the device images with standard user names and standard passwords for the operating system. It is imperative that you change these. Controllers are shipped without a password in the UEFI/BIOS setup. Beckhoff recommends assigning a password here as well.
To disconnect the cables from the Industrial PC, proceed as follows: 1. Make a note of the wiring configuration, if you wish to restore it with another device. 2. Disconnect the data transmission cables from the Industrial PC. 3. Finally, disconnect the grounding strap. Version: 3.2 C6920...

Fig. 22: C6920_tool-less access to battery and storage media You now have access to the battery (1) and storage media (2) (see Fig. 23). Fig. 23: C6920 _Battery and storage media Fan access You can access the fan cartridge from the underside of the Industrial PC.
NOTE Incorrect battery type Inserting the wrong type of battery can damage the device. • Only replace the battery with a replacement battery from Beckhoff Service. • When replacing the battery, make sure that the polarity is correct. NOTE Battery damage Incorrect handling of the motherboard battery can damage it.
If you want to exchange a storage medium according to Beckhoff's recommendation, you must copy the data from the old to the new storage medium. You can use the Beckhoff Service Tool (BST) for this purpose. The BST is a graphical backup and restore program for Industrial PCs with a Windows operating system. You can create an image of your operating system and use it to back up the operating system.
Maintenance 1. Remove the SSD from the PC by pulling forcefully on the protruding Beckhoff sticker (see fig. 27). Fig. 26: C6920_SSD replacement 2. Insert the new SSD into the PC in the same orientation up to the stop. ð You have replaced the SSD.
• Replace the fan cartridge exclusively by a cartridge from Beckhoff Service. The fan cartridge with the two fans ensures optimal cooling of the Industrial PC. Order a new fan cartridge exclusively from Beckhoff. To do this, contact Beckhoff Service (see Chapter 10.1 Service and support [} 47]).
