Safety
General safety
All work on electrical systems or operating equipment may only
be carried out by a specially qualified electrician according to the
applicable electrotechnical regulations.
The safety of the system in which the SENSORswitch is integrated
is the responsibility of the operator.
Notes and symbols used
Warning notes in relation to personal injury / material damage are
formulated according to the "SAFE” principle. This means they
contain information on the type and source of the hazard, potential
consequences as well as how to avoid and avert danger. The
following hazard classifications apply in the safety notes:
DANGER
Danger designates a hazardous situation, which,
if ignored, will lead to death or serious injury. The
symbol next to the warning indicates the type
and source of the danger.
WARNING
Warning designates a hazardous situation,
which, if ignored, may lead to death or serious
injury. The symbol next to the warning indicates
the type and source of the danger.
CAUTION
Caution designates a hazardous situation, which,
if ignored, may lead to injury. The symbol next to
the warning indicates the type and source of the
danger.
NOTICE
