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.
