The natural convection of the ambient air is sufficient for operating the
subassemblies. An adequate entry of the air underneath the device and
unobstructed exit above must always be ensured.
For installation in sealed housings the heat loss arising must be dissipated
through the housing surfaces! If this cannot be guaranteed, a forced airflow
is mandatory.
When used at greater heights (> 1000 m above sea level) the reduced air
pressure (< 900 hPa) requires a reduction in the permitted ambient
temperature of 1 K per 300 m.
The system is supplied as an open installation component. Suitable
measures must be taken at the installation location to protect the
component from dust. For most applications a regularly serviced filter in the
incoming air of the installation location is sufficient. With conductive dust
or in aggressive ambient air the use of a sealed cooling circuit using heat
exchangers or an air conditioned switch cabinet are required.
The installation position must be vertical to ensure adequate ventilation.
A clearance of at leats 80 mm above and below the module should be
retained; for vertically orientated rows of modules the distance between the
carrier rails should be 180 mm.
