Mounting the accessories

To protect the end positions against uncontrolled excess travel:
• Check the necessity of proximity sensors (hardware limit switches).
If proximity sensors are used as limit switches:
• Preferably use proximity sensors with normally-closed function.
This protects against excess travel beyond the end position, if the proximity sensor cable is broken.
If proximity switches are used as reference switches:
• Use proximity sensors that correspond to the input of the controller being used.
• Use proximity sensors with switch lug aB (è Assembly instructions for the accessory).

• Avoid external influences from magnetic or ferritic parts in the vicinity of the proximity sensors (min­
imum distance of 10 mm from the slot nuts).
• Protect the end positions. Attach emergency buffers or shock absorbers to the shock absorber re­
tainer.
• Avoid contamination. Use slot covers in all unused slots.
