Figure 10-2 Ventilation clearances
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 by the components from the bottom (cool area) to the top (area
warmed through 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 ventilation clearance above and below must be ensured.
