WARNING
• All electrical and mechanical installation/maintenance operations
should be carried out by trained and experienced personnel.
• Disconnect the power supply before installation or maintenance.
• Appropriate safety equipment should be known by the service
engineer.
• Make sure that the connected power source fulfils the technical
specifications in this manual..
• Never connect the limit switch to an AC supply!
Important: The CAXE limit switch has no overload or re-
verse polarity protection and must only be used with DC
supply voltage.
As an extra precaution, a fast acting fuse with a value of ≤
0,1 AF could be placed in series with each CAXE. This will
protect the limit switches from being damaged by over
current.
