General

Electrical cabinets can be cooled, using among other things the following:
• filtered fans
• heat exchangers or
• cooling units.
The decision in favor of one of these methods will depend on the prevailing ambient
conditions and the cooling power required.
The air routing within the electrical cabinet and the cooling clearances specified here must
be observed. No other components or cables must be located in these areas.
Caution
If you do not observe the guidelines for installing SINAMICS equipment in the cabinet, this
can reduce the service life of the equipment and result in premature component failure.
You must take into account the following specifications when mounting/installing SINAMICS
components:
• Cooling clearance
• Cable routing
• Air guidance, air-conditioner
