Safety
Safety-related systems
The use of PLCs in safety-related systems requires specific measures. Wherever a PLC is to be used
in a safety-related system, the user must be given comprehensive advice by the PLC manufacturer in
addition to information on any available standards or regulations regarding safety installations.
Before starting any work on devices, switch off all power feeds, including to peripherals.
Keep all ventilation holes unobstructed.
Failure in certain components in an electronic control system may result in uncontrolled and/or unpre-
dictable operational behaviour.
All types of failure must be considered at the system level and the associated preventative
measures identified.
If necessary, request information from your automation system provider.
