For your safety
WARNING!
Potential loss of safety function during adjustment and repair work!
When carrying out adjustment and repair work, make sure that the power
supply of the plant is switched off and protected against switching on again.
WARNING!
Loss of safety function due to manipulative use of substitute actuating ele-
ments!
When substitute actuating elements are used, these have to be installed as
described in chapter
Initial installation of safety switch [
31]
. When sub-
stitute actuating elements are used in a manipulative way to defeat the pro-
tective device, operating the plant presents a threat to life.
The operator has to consider this in the hazard analysis and he must de-
termine possible countermeasures.
