2.4 Obligations of the operator
• The owner must ensure that persons who assemble, operate, disassemble, or
maintain products must not consume any alcohol, drugs, or pharmaceuticals
that may affect their ability to respond.
• The owner must ensure that PPE is used. Observe all specifications for the
overall system.
2.5 Personnel qualifications

2.6 Hazards
2.6.1 Danger of injury
Risk of burns due to hot surfaces
• Do not touch the product or any connected parts during operation (accident
prevention).
• Allow the product to cool down before carrying out any work.
Danger of injury due to contaminated compressed air
• Ensure that the specified air quality class for the flow medium is maintained.
Contamination in the compressed air leads to damage to the product, mea-
surement errors and malfunctions. Unintended signals at the outputs lead to
personal injury or material damage (injury prevention, material protection).
2.6.2 Material damage
Damage due to too high mechanical loads
• Never twist or bend the product and add-on parts, or mount them when they
are under tension.
• Do not use the product as a handle or step.
• Do not position any objects on the product.
Damage due to control network malfunction
Products with Ethernet connection are designed to be used on specific industrial
control networks. Observe the following safety measures:
• Always follow industry best practices for network segmentation.
• Avoid exposing products with Ethernet connection directly to the Internet.
• Minimize internet and business network exposure for all control system de-
vices and/or control systems.
• Ensure that products, control system devices and/or control systems are not
accessible from the Internet.
• Locate control networks and remote devices behind firewalls and isolate them
from the business network.
• If remote access is required, only use secure methods such as Virtual Private
Networks (VPNs).
NOTICE! Recognize that VPNs and other software-based products may have
vulnerabilities. A VPN is only as secure as the connected devices it serves. Al-
ways use the current version of the VPN, the firewall and other software-based
products.
• Ensure that the latest released software and firmware versions are installed on
all products connected to the network.
