Safety instructions for Control Units and Control Unit Adapters

Fire through overheating due to 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
may be shortened.
• It is essential that you maintain 50 mm ventilation clearances above and below the
• Ensure that the air openings are not blocked by connecting cables.
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
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
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.
• A functional equipotential bonding conductor with a cross-section of at least 10 mm²
