Figure 9-3 Cooling clearances
9.8.2 Ventilation
The SINAMICS equipment is ventilated separately by means of integrated fans and is in
some cases cooled by means of natural convection.
The cooling air must flow through the components vertically from bottom (cooler region) to
top (region heated by operation).
If filtered fans, heat exchangers, or air conditioners are used, 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 cooling clearance above and below must be observed.
Note
Cables must not be routed on the components; the ventilation meshes must not be covered.
Cold air must not be allowed to blow directly onto electronic equipment.
