Safety instructions for Control Unit CU305
Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
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
may be shortened.
• It is essential that you ensure 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.
Danger to life due to software manipulation when using exchangeable storage media
Storing files on exchangeable storage media poses an increased risk of infection, e.g. with
viruses and malware. Incorrect parameter assignment can cause machines to malfunction,
which can lead to injuries or death.
• Protect files stored on exchangeable storage media from malicious software using
appropriate protection measures, e.g. virus scanners.
