Mounting surface
► During installation, ensure that the pollution degree is 2 or better� Pollution
degree 2 is a light, common contamination which can be caused by occasional
thawing or hand perspiration (DIN EN 60664-1)�
4.4 Heat dissipation
► Ensure sufficient heat dissipation as the internal heating of the electronics
is conducted away via the housing� The heat dissipation mainly takes place
via the bottom of the housing� The housing is built in such a way that, when
mounted on a flat surface, the heat can be dissipated through the bottom�
