Warning concept
This manual contains information that you should observe to ensure your own personal safety as well as to
avoid material damage. The notes referring to your personal safety are highlighted in the manual by a
triangular safety alert symbol; notices referring to property damage only have no safety alert symbol.
Depending on the hazard level, warnings are displayed in descending order as follows.
DANGER
Indicates that death or serious injury will result if the appropriate precautionary measures are not taken.
WARNING
indicates that death or serious injury can result if the appropriate precautionary measures are not taken.
CAUTION
with a triangular safety alert symbol indicates that minor personal injury can result if the appropriate
precautionary measures are not taken.
CAUTION
without a triangular safety alert symbol indicates that property damage may result if the appropriate
precautionary measures are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
In the event of a number of levels of danger occurring simultaneously, the warning corresponding to the
highest level of danger is always used. A warning with a triangular safety alert symbol indicating possible injury
to personnel may also include a warning relating to property damage.
