3.2 Explaining signal words and safety alert symbol
The safety instructions in this documentation contain specific signal words (dan-
ger, warning, caution, notice) and, if necessary, a safety alert symbol (according
to ANSI Z535.6-2006).
The signal word is used to draw attention to the safety instruction and also pro-
vides information on the severity of the hazard.
The safety alert symbol (a triangle with an exclamation point), which precedes
the signal words danger,warning and caution is used to alert the reader to per-
sonal injury hazards.
DANGER
In case of non-compliance with this safety instruction, death or serious injury
will occur.
WARNING

The IndraControl extension modules can be used for complex connections to
controls that cannot be operated at the S20 bus, such as interface modules to
Profinet, Profibus, CAN and Sercos or Safety connection.
The IndraControl extension modules may only be operated under the mounting
and installation conditions, the position and the ambient conditions (tempera-
ture, degree of protection, humidity, EMC etc.) specified in this documentation.
