Special conditions
• Ensure that additional measures for
components are taken, which are
used in an environment involving:
– dust, caustic vapors or gases
– ionizing radiation
• Ensure that the permissible
temperature range of the connecting
cable is correct dimensioned
depending on the installation position
and current intensity, because the
clamping point temperature at 10 A
can be up to 25 °C above the
expected surrounding air temperature.
