Legal notes
Warning note concept
This manual comprises notes which must be observed for your personal safety and for preventing material
damage. Notes for your personal safety are marked with a warning triangle, those only for preventing
material damage appear without a warning triangle. Depending on the level of hazard, the warning notes
are shown in reverse order of seriousness, as follows.
DANGER
means, that death or serious injury will result, if the appropriate preventive action is not taken.
WARNING
means that death or serious injury may result, if the appropriate preventive action is not taken.
CAUTION
means that a slight injury may result, if the appropriate preventive action is not taken.
NOTICE
means that material damage may result, if the appropriate preventive action is not taken.
Where there is more than one hazard level, the warning note for whichever hazard is the most serious is
always used. If in a warning note a warning triangle is used to warn of possible personal injury, a warning
of material damage may be added to the same warning note.
Qualified personnel
The product or system to which this documentation relates may be handled only by persons qualified for
the work concerned and in accordance with the documentation relating to the work concerned, particularly
the safety and warning notes contained in those documents.
Qualified personnel must be specially trained and have the experience necessary to recognise risks
associated with these products and to avoid possible hazards.
