Safety instructions for Control Units and Control Unit Adapters
WARNING
Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
WARNING
Danger of fire through overheating for insufficient ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. Further, increased failures can occur and the service life of units/systems
shortened.
• It is essential that you maintain 50 mm ventilation clearances above and below the
Control Unit and Control Unit Adapter.
• Ensure that the air openings are not blocked by connecting cables.
WARNING
Danger to life due to software manipulation when using exchangeable storage media
Storing files onto exchangeable storage media amounts to an increased risk of infection,
e.g. with viruses and malware. As a result of incorrect parameterization, machines can
malfunction, which in turn can lead to injuries or death.
• Protect files stored on exchangeable storage media from malicious software by with
suitable protection measures, e.g. virus scanners.
NOTICE
Memory card damage caused by electric fields or electrostatic discharge
Electrical fields or electrostatic discharge may result in the memory card being damaged.
• When removing and inserting the memory card, always observe the ESD regulations.
NOTICE
Risk of component destruction as a result of high leakage currents
The Control Unit or other PROFIBUS and/or PROFINET nodes can be destroyed, if
significant leakage currents flow via the PROFIBUS or PROFINET cable.
• Use a functional equipotential bonding conductor with a cross-section of at least 25 mm²
between components of a plant or system that are located at a distance from each
other.
