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