For hard and stiff payloads (steel):
Note
If the aluminium slide is bent against a curved
payload, the service life of the guide will be reduced.
Use a payload with a flat mounting surface.
Flatness t = 0.01 mm.

Installing the external accessories
To protect the end positions against uncontrolled overtravel:
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 overtravel of 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 aJ (è Assembly instructions of the accessory).
Mounting
in the grooves 9 (è Fig. 1)
Tab. 3
Avoid external influences from magnetic or ferritic parts in the vicinity of the proximity sensors
(minimum distance of 10 mm from the slot nuts).
Avoid contamination and use slot covers in all unused slots.
