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
IP 54. 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 dis-
tance enables the heat from the evaluation unit to dissipate.
Important!

Ì
When mounting several read heads, observe the stipulated minimum distance to avoid mutual in-
terference.

If the actuator is installed flush, the switching distance changes as a function of the installation
depth and the guard material.

Note the following points:
Ì
Actuator and read head must be fitted so that
- the front faces are at the minimum assured operating distance 0.8 x S
tion Actuating ranges). 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 actuating range for the related actuator.
- a hazard is excluded until the assured release distance (S
- the actuator is positively mounted on the 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 fastenings of 1 Nm. For
read heads/actuators made of PE-HD, the maximum tightening torque is only 0.5 Nm.
