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.
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).
