Installation
Caution!
Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective.
Ì
On this topic pay attention in particular to the measures for reducing the pos-
sibility of bypassing according to EN 1088:1995.A2:2008, sec. 5.7.
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 standard rails.
Ì
If several evaluation units are mounted side by side in a control cabinet with-
out air circulation (e.g. fan), a minimum distance of 10 mm must be main-
tained between the evaluation units.
The distance enables heat from the evaluation unit to dissipate.
Caution!
Risk of damage to equipment as a result of incorrect installation. Read heads
or actuators must not be used as a mechanical end stop.
Ì
Fit an additional end stop for the movable part of the safety guard.
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 dis-
tance to avoid mutual interference.
