Cooling

14.7.1

General

The following devices are available as cooling equipment:
● Internal liquid cooling (in preparation)
● External air cooling
● External liquid cooling
The decision in favor of one of these methods will depend on the prevailing ambient
conditions and the cooling power required.
The ventilation clearances stated here must be observed. No other components or cables
must be located in these areas.
If you do not observe the guidelines for installing SINAMICS equipment in the cabinet, this
can significantly reduce the service life of the equipment and result in premature
component failure.
Note
When the line reactor is being installed, it is best not to install it in the same cabinet (max.
distance approx. 0.5 m). If necessary, it can be installed on the heat sink.
You must take into account the following specifications when installing a SINAMICS drive
line-up:
● Ventilation clearance
● Cable routing
● Air guidance
Booksize cold-plate power units
