Mounting
Pay attention to the following safety notes:
Sensor and actuator shall not be used as a mechanical stop.
Prevent tampering such as adjusting, removing or bypassing the
device that will prevent correct function in any manner. The conse-
quences otherwise may be injuries or death.
The availability of spare actuators may jeopardize the integrity of the
safety system (risk of tampering). This situation may result in injuries
or death, damage or financial losses. Organize suitable monitoring,
procedures and alternative protective measures to regulate the
usage and availability of these replacement actuators.
Mounting of multiple safety switches
On mounting several safety switches, observe the minimum distance
stipulated between the individual systems of 75 mm (with M18 actu-
ator) or 100 mm (with M30 actuator) to prevent mutual interference.
