5.1.3 Installing external accessories
To protect the end positions against uncontrolled overrunning:
• Check whether proximity sensors are required (hardware limit switches).
If proximity sensors are used as limit switches:
• Preferably use proximity switches with normally-closed function.
These will protect an EGC with a fractured proximity switch cable from overrunning the end position.
If proximity switches are used as reference switches:
• Use proximity switches that correspond to the input of the controller being used.
• Use inductive proximity switches with switch lug aE (
used).

• Avoid external influence caused by magnetic or ferrite parts in the vicinity of the proximity switches
(minimum distance of 10 mm to the slot nuts).
To protect the end positions:
• Use emergency buffer or shock absorber (
To avoid contamination:
• Use slot covers in all unused grooves.

Note
If used in safety-relevant applications, additional measures are necessary. In Europe, for
example, the standards in the EC machinery directive must be observed.
Without additional measures corresponding to statutory minimum requirements, the
product is not appropriate as a safety-related part of control systems.
