Chapter 2 • Intended use
These products are developed and produced exclusively for training and development in the area of automation.
Any use beyond this is not permitted, in particular the integration of these products or parts thereof in machines,
systems or other devices and processes. B&R does not assume liability for damages of any kind that occur when
using the products outside of training and development or for harm that results from modifying the products. Ex-
pansions using products from the ETA system or ETA light system series are permitted.
In addition, the products are only permitted to be used in closed rooms (such as laboratories, offices and class-
rooms) that do not require separate protective equipment. Trainers shall inform the trainees of the relevant safety
guidelines and precautions before using the product.
1 Protection against electrostatic discharge
Electrical assemblies that can be damaged by electrostatic discharge (ESD) must be handled accordingly.
1.1 Packaging
•Electrical assemblies with housing:
Do not require special ESD packaging but must be handled properly (see "Electrical assemblies with hous-
ing").
•Electrical assemblies without housing:
Are protected by ESD-suitable packaging.
1.2 Regulations for proper ESD handling
Electrical assemblies with housing
•Do not touch the connector contacts of connected cables.
•Do not touch the contact tips on circuit boards.
Electrical assemblies without housing
The following applies in addition to "Electrical assemblies with housing":
•All persons handling electrical assemblies and devices in which electrical assemblies are installed must
be grounded.
•Assemblies are only permitted to be touched on the narrow sides or front plate.
•Always place assemblies on suitable surfaces (ESD packaging, conductive foam, etc.). Metallic surfaces
are not suitable surfaces!
•Assemblies must not be subjected to electrostatic discharges (e.g. due to charged plastics).
•A minimum distance of 10 cm from monitors or television sets must be maintained.
•Measuring instruments and devices must be grounded.
•Test probes of floating potential measuring instruments must be discharged briefly on suitable grounded
surfaces before measurement.
Individual components
•ESD protective measures for individual components are implemented throughout B&R (conductive floors,
shoes, wrist straps, etc.).
•The increased ESD protective measures for individual components are not required for handling B&R
products at customer locations.
2 Regulations and measures
Electronic devices are generally not failsafe. If the programmable logic controller, operating or control device or
uninterruptible power supply fails, the user is responsible for ensuring that connected devices (such as motors)
are brought to a safe state.

Intended use • Security concept
Chapter 2
Intended use
ETAL611.1T10-1 user's manual V1.00 5
When using programmable logic controllers as well as when using operating and monitoring devices as control
systems in conjunction with a Soft PLC (e.g. B&R Automation Runtime or similar product) or Slot PLC (e.g. B&R
LS251 or similar product), the safety measures that apply to industrial controllers (protection by protective equip-
ment such as emergency stops) must be observed in accordance with applicable national and international regu-
lations. This also applies to all other connected devices, such as drives.
3 Transport and storage
During transport and storage, devices must be protected against undue stress (mechanical stress, temperature,
humidity, aggressive atmosphere, etc.).
Devices contain components sensitive to electrostatic charges that can be damaged by improper handling. It is
therefore necessary to provide the required protective measures against electrostatic discharge when installing
or removing these devices.
4 Operation
4.1 Protection against contact with electrical parts
Before switching on programmable logic controllers, operating and monitoring devices and uninterruptible power
supplies, it must be ensured that the housing is properly connected to ground potential (PE rail). The ground
connection must also be made if the operating and monitoring device and uninterruptible power supply are only
connected for testing purposes or only operated for a short time!
4.2 Ambient conditions - Dust, moisture, aggressive gases
The use of operating and monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels) and uninterruptible
power supplies in dusty environments must be avoided. This can otherwise result in dust deposits that affect the
functionality of the device, especially in systems with active cooling (fans), which may no longer ensure sufficient
cooling.
The presence of aggressive gases in the environment can also result in malfunctions. In combination with high
temperature and relative humidity, aggressive gases – for example with sulfur, nitrogen and chlorine components
– trigger chemical processes that can very quickly impair or damage electronic components. Blackened copper
surfaces and cable ends in existing installations are indicators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality, operating and monitoring
devices such as Automation Panels or Power Panels are protected on the front against the ingress of dust and
moisture when installed correctly (e.g. cutout installation). The back of all devices must be protected against the
ingress of dust and moisture, however, or the dust deposits must be removed at suitable intervals.
4.3 Programs, viruses and malicious programs
Any data exchange or installation of software using data storage media (e.g. floppy disk, CD-ROM, USB flash
drive) or via networks or the Internet poses a potential threat to the system. It is the direct responsibility of the user
to avert these dangers and to take appropriate measures such as virus protection programs and firewalls to protect
against them and to use only software from trustworthy sources.
5 Security concept
B&R products communicate via a network interface and were developed for integration into a secure network. The
network and B&R products are affected by the following hazards (not a complete list):
•Unauthorized access
•Digital intrusion
•Data leakage
•Data theft
•A variety of other types of IT security breaches
It is the responsibility of the operator to provide and maintain a secure connection between B&R products and the
internal network as well as other networks, such as the Internet, if necessary. The following measures and security
solutions are suitable for this purpose:
•Segmentation of the network (e.g. separation of the IT and OT networks)
•Firewalls for the secure connection of network segments

Intended use • Security concept
6 ETAL611.1T10-1 user's manual V1.00
•Implementation of a security-optimized user account and password concept
•Intrusion prevention and authentication systems
•Endpoint security solutions with modules for anti-malware, data leakage prevention, etc.
•Data encryption
It is the responsibility of the operator to take appropriate measures and to implement effective security solutions.
B&R Industrial Automation GmbH and its subsidiaries are not liable for damages and/or losses resulting from, for
example, IT security breaches, unauthorized access, digital intrusion, data leakage and/or data theft.
Before B&R releases products or updates, they are subjected to appropriate functional testing. Independently of
this, the development of customized test processes is recommended in order to be able to check the effects of
changes in advance. Such changes include, for example:
•Installation of product updates
•Notable system modifications such as configuration changes
•Deployment of updates or patches for third-party software (non-B&R software)
•Hardware replacement
These tests should ensure that implemented security measures remain effective and that systems behave as
expected.
