Ventilation - Siemens S120 Manual

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.
NOTICE
Damage caused by overheating
Overheating can cause system damage.
• Install the components with the specified orientation.
• Maintain the minimum clearances to other components.
• Install a suitable ventilation in the control cabinet in order to dissipate the power loss.
• Install suitable air filters and keep the heat sink clean.
• Ensure that the components are provided with adequate cooling air through the cooling
• Ensure that the cooling air flow is not blocked by other devices or mixes with the
