4.3.2
Grounding of the Industrial PC
Potential differences are minimized and electrical currents are diverted to the ground through grounding or
potential equalization of electronic devices. This is to prevent dangerous touch voltages and electromagnetic
interference.
At the lower end of the Industrial PC mounting plate there is an grounding screw (see also chapter 3.1
Structure [} 10]), via which the functional earth of the PC can be connected. Use cables with a cross-section
of at least 4 mm2 to connect the protective conductor.
Protective earth
Establish the low-resistance protective earth of the Industrial PC via the voltage connection, thus avoiding
dangerous contact voltages. There is a pin in the voltage socket for the protective earth (PE).
EMC
NOTE
Hardware damage due to electromagnetic interference
Using the Industrial PC without functional earthing can lead to hardware damage due to electromagnetic in-
terference.
• Only use the device with functional earthing.
Electromagnetic compatibility (EMC) of the industrial PC includes on the one hand not affecting other
devices and equipment by electromagnetic interference and on the other hand not being disturbed by
electrical or electromagnetic effects itself.
For this purpose, the Industrial PC must comply with certain protection requirements. The Industrial PC has
EMC interference immunity according to EN 61000-6-2. The EMC interference emission of the device meets
the requirements of EN 61000-6-4.
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.

all data transfer cables.
Connecting the power supply
Cables with a maximum cable cross-section of 1.5 mm2 must be used for connecting the power supply. To
achieve the lowest possible voltage drop on the supply line, we recommend connecting the maximum
possible cross-section. In case of larger distances between the power source and the PC, take into account
the voltage drop in relation to the cable cross-section as well as fluctuations in your supply voltage in order to
ensure that the voltage at the power supply unit does not fall below 22 V.
Proceed as follows to connect the 24 VDC power supply unit:
1. Check the correct voltage of your external power supply.
2. Install the power cable.
3. Plug the power cable into the voltage socket of the Industrial PC.
4. Screw the power cable to the voltage socket of the Industrial PC.
5. Connect the PC to your external 24 V power supply.
6. Switch on the 24 V power supply.
7. Measure the voltage on the power supply plug of the PC.

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
• C9900-U332: Battery pack for PCs with low power consumption without using the UPS output on the
PC
When using the C9900-U330 battery pack, you can use the UPS output of the power supply unit (UPS
Output). The method of connecting different components can be taken from the wiring diagram in fig. 13.

So that the Industrial PC still has a monitor output in case of a power failure, a Control Panel can be
connected to the UPS output of the power supply unit. Even after a power failure there is a voltage of 24 VDC
between the 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.

Switching the Industrial PC on and off
First switching on and driver installation
NOTE
Public networks
Connecting the PC to public networks without additional protective measures can compromise the safety of
the device.
• Protect the PC before connecting it to public networks.
The Industrial PC is started when the system is switched on or when the power supply is connected.
When you switch on the Industrial PC for the first time, the pre-installed operating system (optional) will be
started. For any additional hardware you have connected, you have to install the drivers yourself afterwards.
In addition, the Beckhoff Device Manager starts automatically. The Device Manager is a software from
Beckhoff that supports you in configuring the PC.
If you have ordered the PC without an operating system, you must install this and the driver software for the
additional hardware you have connected and for the devices in the PC yourself. Please follow the
instructions in the documentation for the operating system and the additional devices.
Switching off the Industrial PC
NOTE
Data loss due to running software
Switching off the Industrial PC before the running software is terminated and the operating system is shut
down can lead to data loss.
• Quit the running software and shut down the operating system before switching off the PC.
NOTE
Shortened battery life due to switching off the power supply
If the power supply is simply switched off, the operating system shuts down via the battery. With daily use,
this significantly shortens the life of the battery.
• 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.
If you have an Industrial PC with a UPS and simply switch off the power supply, the operating system shuts
down via the battery. With frequent use, this shortens the life of the battery.
To shut down the operating system properly, you can install an additional ON/OFF switch next to the
machine's main switch to turn the machine on and off. The main switch can thus remain switched on in
principle and thus ensures that the PC is still supplied with power during the shutdown of the operating
system.
If 24 V is then applied to the input PC_ON via a switch, the operating system shuts down properly. The
PC_ON signal is inverted, i.e. the operating system shuts down when 24 V is applied.
Once the operating system has shut down, the PC power supply unit sets the output power status from 24 V
to 0 V. This indicates that the shutdown is complete and you can turn off the power supply. Via the output,
you can switch, for example, a contactor that switches off the entire system. The maximum load for the
Power Status output is 0.5 A and a suitable fuse should be provided.
You can assign different access rights to all users in the operating system and in the application software.
Since there is a risk of data loss if the Industrial PC is switched off incorrectly, assign the rights advisedly. A
user who is not allowed to terminate the software should not be allowed to switch off the Industrial PC.
UPS software components
26
Version: 2.5
Commissioning
To operate the power supply unit as a UPS, the UPS driver software with the corresponding drivers must be
installed on the Industrial PC. The software and drivers are already installed on delivery of the PC with
operating system. Otherwise, you will have to install them yourself.
You can obtain the software and drivers either online for download via the following link: https://
download.beckhoff.com/download/software/Industrial_PC/OS_Support/Driver_DVD or you can contact
Beckhoff Service (service@beckhoff.com), which will provide you with the software and drivers. The driver
software comes with a detailed help function. 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:

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.
Please note the following:
• Passwords should be unique for each user and service.
• Only change passwords after an incident in which passwords have become known without
authorization.
• Train the device users in the use of passwords.
A secure password has the following characteristics:
• Password complexity: the password should contain capital and lower-case letters, numbers,
punctuation marks and special characters.
• Password length: the password should be at least 10 characters long.

Use of incorrect spare parts
The use of spare parts not ordered from Beckhoff Service can lead to unsafe and faulty operation.
• Only use spare parts that you have ordered from Beckhoff Service.
Beckhoff Industrial PCs are manufactured from components of the highest quality and robustness. They are
selected and tested for best interoperability, long-term availability and reliable function under the specified
environmental conditions.
Nevertheless, some components of the Industrial PC may be subject to a limited service life if they are
operated under certain conditions, such as more demanding ambient conditions during operation or during
storage, or if they are out of service for long periods of storage.
Beckhoff therefore recommends replacing some of the Industrial PC components after the time after which
predictions of the remaining service life of such components can no longer be reliably calculated.
These are the following components:
• Battery and battery pack
• Storage media
The following table provides recommendations for the regular, precautionary replacement of the PC
components:

Beckhoff is excluded from liability in the event of possible damage occurring during maintenance work. In
order to avoid damage caused by electrostatic discharge when replacing device components, protective
measures are recommended. Below are some suggestions.
ESD protection
NOTE
Electrostatic discharge
The replacement of device components without ESD protection can lead to functional impairment and de-
struction of the device.
• If possible, apply ESD protection measures during maintenance work.
When working on electronic devices, there is a risk of damage due to ESD (electrostatic discharge), which
can impair the function or destroy the device.
Protect the Industrial PC and create an ESD-protected environment in which any electrostatic charges are
discharged to the ground in a controlled manner and charging is prevented.
An ESD-protected environment can best be created by setting up ESD protection zones. The following
measures serve this purpose:
• ESD-compliant floors with sufficient conductivity to the reference potential PE;
• ESD-compatible work surfaces such as tables and shelves;
• Wrist grounding strap, especially for sedentary activities;
Version: 2.5
33
Maintenance
• grounded and electrostatically dissipating equipment and operating materials (e.g. tools) within the
ESD protection zone.
If it is not possible to create an ESD protection zone, you can still protect the device against ESD damage.
For example, the following measures can be used:
• Use conductive mats connected to the ground potential as underlays.
• Dissipate possible charges from your own body by touching earthed metal (e.g. control cabinet door).
• Wear a wrist grounding strap.
• Only remove new electronic components from the ESD packaging (tinted plastic bag) after putting on
the wrist grounding strap.
• Do not walk around with electronic components in your hand if they are not in ESD packaging.

Replacing the storage media
New storage media should only be obtained from Beckhoff Service (see Chapter 10.1 Service and support
[} 40]).
The old storage media must be disposed of in accordance with the national electronic waste regulations.
Data transfer before replacement
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. You can then
restore the images created in this way. The BST is available on a bootable BST USB flash drive. This
includes Windows and a backup software. Select the size of the BST USB flash drive according to the size of
the backup copy of your operating system. You can then keep the flash drive as a backup copy. For this
purpose, the BST USB flash drives with SLC flash are designed for a particularly long data preservation. For
more information on the function of the BST, please refer to the corresponding documentation.
If your storage medium is defective and there is no backup, Beckhoff Service can provide you with a fresh
Windows image. For this to be possible, the Beckhoff IPC must already have been shipped with a valid
operating system license. When installing the fresh image, the applications must be reinstalled.
Replacing the CFast
Chapter 7.2.1 Access to device components [} 35] shows how you can access the CFast.
To change the CFast, follow the steps below, which are shown in fig. 20:
