NOTICE
Device damage due to improper installation or unsuitable ambient conditions.
Ì Read heads and actuators must not be used as a mechanical end stop.
Ì Observe EN ISO 14119:2013, sections 5.2 and 5.3, for information about fastening the safety
switch and the actuator.
Ì Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for by-
passing an interlocking device.
Ì The evaluation unit must be mounted in a control cabinet with a minimum degree of protection of
IP54. A snap-in element on the rear of the device is used for fastening to a mounting rail.
Ì If several evaluation units are mounted side by side in a control cabinet without air circulation
(e.g.fan), a minimum distance of 10mm must be maintained between the evaluation units. This
distance enables the heat from the evaluation unit to dissipate.
Important!
Ì From the assured switch-off distance S
ar
, the safety outputs are safely shut down.
Ì When mounting several read heads, observe the stipulated minimum distance to avoid mutual in-
terference.

Note the following points:
Ì Actuator and read head must be tted so that
- 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 maintained in
case of a side approach direction. See section Typical operating distance for the related actuator.
- a hazard is excluded until the assured switch-off distance (S
ar
) is reached when the safety guard is open.
- the actuator is positively mounted on the safety guard, e.g.by using the safety screws included.
- 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.
