WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances
that you have read the latest safety data sheets provided
by the manufacture of the hazardous substance. The
actions required are described in the safety data sheet.
Check the safety data sheet regularly and replace, if
necessary, as the hazard potential of a substance can
be re-evaluated at any time based on new findings.
The system operator is responsible for ensuring that
these safety data sheets are available and that they are
kept up to date, as well as for producing an associated
hazard assessment for the workstations affected.
WARNING!
Live parts
Cause: Incorrectly performed installation work can lead

for ensuring compliance and implementation.
