  For mounting with the spacer (6GT2690-0AA00), use a stainless steel M5 screw to avoid 
damaging the MDS in high temperatures (expansion coefficient). 
4)
  In higher temperatures (> +80 °C), observe the expansion coefficient of all materials in order to 
prevent damage to the MDS due to fastening. 
5)
  Note that no processing is possible at temperatures of +140 °C or higher.
