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 connecting cable is correctly dimensioned
The permissible temperature range of the connecting cable must be dimensioned
depending on the mounting position and current intensity because the
temperature of the terminal connection can be up to 24 °C above the expected
surrounding air temperature (at 10 A via the power jumper contacts).
