3. Mounting
3.1 General mounting instructions
• Fitting is only authorised in a de-energised condition.
• Do not use the sensor and the actuator as a mechanical backstop.
• Any mounting position, provided that the active surfaces are opposite.
• Inseparably fix the sensor and the actuator to the safety guard.
• Do not install the safety sensor and the actuator in strong magnetic
fields.
• If possible, do not mount the sensor and the actuator on ferromagnetic
material. When the sensor and the actuator are installed on
ferromagnetic material, variations can be expected in the limit
distances. The use of a non-magnetic spacer of at least
5 mm thick must be used. The use of non-magnetic fixing screws is
recommended also.
• 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.
Also suitable for concealed mounting behind
non-ferromagnetic covers.

3.4 Adjustment
Align the central markings of the safety sensor and the actuator
with each other. The LED can only be used as rough setting tool.
The correct functionality of both safety channels must 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
