3. Mounting
3.1 General mounting instructions
Please observe the relevant requirements of the
standards ISO 12100, ISO 14119 and ISO 14120.
Ensure the safety sensor and actuator is mounted on a flat surface.
The universal mounting holes provide for a variable mounting by means
of M4 screws (tightening torque 2.2 … 2.5 Nm).
The component can be mounted in any position. The labelled surfaces
of the safety sensor and the actuator have to be opposite. The safety
sensor must only be used within the assured switching distances
≤ s
ao
and ≥ s
ar
.
The actuator must be permanently fitted to the safety guards
and protected against displacement by suitable measures
(e.g. tamperproof screws, gluing, drilling of the screw heads).
To avoid any interference inherent to this kind of system and any
reduction of the switching distances, please observe the following
guidelines:
• The presence of metal chips in the vicinity of the sensor is liable to
modify the switching distance.
• Keep away from metal chips.
• Minimum distance 100 mm between two safety sensors
as well as other systems with same frequency (125 kHz)
