3. Mounting
3.1 General mounting instructions
During fitting, the requirements of ISO 14119
must be observed.
• Fitting is only authorised in a de-energised condition
• Do not use the sensor and the actuator as a mechanical backstop
• Any mounting position; Prerequisite: install of the magnet at the front
end of the sensor
• The safety sensor and the actuator must be fitted in a concealed
mounting position in order to avoid a neutralisation of the sensor's
function by simple means.
• Screw both nuts in the provided mounting holes to fix the safety sen
-
sor (max. tightening torque 500 Ncm)
To avoid any interference inherent to this kind of system and any reduc-
tion of the switching distances, please observe the following guidelines:
• If possible, do not install the safety sensor and the actuator on a
ferromagnetic material.
• Do not install the safety sensor and the actuator in strong
magnetic fields
• Do not subject the safety sensor and actuator to extreme vibrations
and shocks
• Keep away from metal chips
• The mounting distance between two sensors should always be at
least 50 mm.
Safety sensor and actuator must be permanently fitted to the
safety guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the screw
heads).

3.3 Axial misalignment
A horizontal and vertical misalignment of the safety sensor and the
actuator is tolerated. The possible misalignment depends on the dis-
tance of the active surfaces of the sensor and the actuator. The sensor
remains active within the tolerance range.
The specified switching distances refer to opposedly mounted safety
sensors and actuators. Different arrangements are possible, however
this may lead to different switching distances.

3.4 Adjustment
The correct functionality must always be checked by means of the
connected safety-monitoring module.
Recommended Adjustment
Align the safety sensor and actuator
at a distance of 0.5 x s
