4 Installation
Depending on the model the sensor may be installed flush
(per IEC60947-5-2) or non-flush (per IEC60947-5-2).
WARNING
Failure of the safety function
The safety function of the sensor cannot be assured when using
outside of the defined ambient conditions.
►Use only in accordance with the defined ambient conditions
(see Section 8 Maintenance, Care, and Disposal on page30).
►Use of the sensor in the vicinity of chemical and biological media as well
as ionizing radiation is not permitted.
NOTICE
Improper installation
Flush mounting of the safety sensor BES0574, BES0575 and BES0578
can result in an increase of the switching distance before the outputs
(OSSDs) are released.
►Install the safety sensor according to the specifications described in this
section.
NOTICE
Intended or unintended circumventing of the safety function.
Metallic objects which directly contact the active surface or are in
the release zone of the sensor can result in an unintended activation
of the machine function.
►Prevent intentional circumventing of the safety functions by means such
as covered installation.
►Protect the active surface of the sensor against falling metallic objects
(e.g. by having the active surface pointing down).
►Otherwise use the sensor only after strict evaluation of the accident risk
and documented risk assessment.
