5.2 Ventilation

5.2 Ventilation
The SINAMICS G130 devices are forced-ventilated by means of integrated fans. To ensure
an adequate air supply, suitable openings for the inlet air (e.g. ventilation slots in the cabinet
door) and discharged air (e.g. by means of a hood) must be provided.
The cooling air must flow through the components vertically from bottom (cooler region) to
top (region heated by operation).
You must ensure that the air is flowing in the right direction. You must also ensure that the
warm air can escape at the top. The ventilation clearances specified in the table "Ventilation
clearances for the components" in the previous section must be observed.
Note
Cables must not be routed directly on the components. The ventilation slots must not be
covered.
Cold air must not be allowed to blow directly onto electronic equipment.
NOTICE
