Cooling

Self-cooling
The rated data only apply if the ambient temperature does not exceed 40 °C (104 °F) as a
result of the installation conditions.
Recommendation:
Maintain a gap of 100 mm to adjacent components on at least three sides in order to allow
waste heat to dissipate.
Forced ventilation
Fan connector
Direction of air flow
Only connect the ventilation unit via a suitable motor contactor (not included in the scope of
delivery).
