WARNING

Loss of the safety function due to a faulty mechanical connection between the motor and the safety encoder.
Severe or fatal injuries.
  • To ensure the exclusion of any faults in the mechanical connection between the motor and the safety encoder, comply with the following points in accordance with EN 61800-5-2:
  • Perform a proper disassembly/assembly procedure according to this documentation.
  • Replace worn or damaged components.
  • Adhere to the tightening torques specified in this documentation.

You need the following tools to assemble and disassemble the encoders. Make sure that all the tools are available before you remove/install an encoder.
