Mounting
Important!
Ì From the assured switch-off distance S
ar
, the safety outputs are safely shut
down.
Ì When mounting several safety switches, observe the stipulated minimum
distance to avoid mutual interference.
min. 80mm
Ì If the actuator is installed flush, the switching distance changes as a function
of the installation depth and the safety guard material.

Note the following points:
Ì Actuator and safety switch must be easily accessible for inspection and re-
placement.
Ì The switching operation must only be triggered by the specific actuator desig-
nated for this purpose.
Ì Actuator and safety switch must be fitted so that
Ì the front faces are at the minimum switch-on distance 0.8 x S
ao
or closer
when the safety guard is closed (see section Operating distances). To avoid
entering the area of possible side lobes, a minimum distance is to be main-
tained in case of a side approach direction. See section Typical operating
distance for the related actuator.
Ì when the safety guard is open up to the distance S
ar
(assured switch-off dis-
tance), a hazard is excluded.
Ì the actuator is positively mounted on the safety guard, e.g. by using the
safety screws included.
Ì they cannot be removed or tampered with using simple means.
Ì Pay attention to the maximum tightening torque for the read head or safety
switch and actuator mountings of 1 Nm. For read heads/actuators made of
PE-HD, the maximum tightening torque is only 0.5 Nm.
