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 grilles must not be

covered.

Cold air must not be allowed to blow directly onto electronic equipment.

NOTICE

Air guidance note

Air guidance, as well as the arrangement of and settings for the cooling equipment, must be

chosen in such a way as to prevent condensation even with the highest relative humidity.

If necessary, cabinet enclosure heating may have to be installed.
