1.4 Danger to life due to software manipulation when using removable
storage media
WARNING
Danger to life due to software manipulation when using removable storage media
The storage of files on removable storage media involves a high risk of infection, e.g. via
viruses or malware. Incorrect parameter assignment can cause machines to malfunction,
which can lead to injuries or death.
● Protect the files on removable storage media against harmful software through appropriate
protective measures, e.g. virus scanners.
1.5 Residual risks of power drive systems
When performing the risk assessment for a machine or plant in accordance with the respective
local regulations (e.g. EC Machinery Directive), the machine manufacturer or plant constructor
must take into account the following residual risks associated with the control and drive
components of a drive system:
1. Unintentional movements of driven machine or system components during commissioning,
operation, maintenance and repairs caused by, for example:
– Hardware and/or software errors in the sensors, control system, actuators, and cables
and connections
– Response times of the control system and of the drive
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices / mobile phones in the immediate vicinity of electronic
components
– External influences/damage
– X-rays, ionizing radiation and cosmic radiation
2. Unusually high temperatures, including open flames, as well as emissions of light, noise,
particles, gases, etc., can occur inside and outside the components under fault conditions
caused by, for example:
– Component failure
– Software errors
– Operation and/or environmental conditions outside the specification
– External influences/damage
