12.9.1

General information

The cabinet can be cooled, among others, by using:
● Filter fans
● Heat exchangers
● Refrigerators
● external air cooling
The decision in favor of one of these methods will depend on the prevailing ambient
conditions and the cooling power required.
The air routing inside the control cabinet and the cooling clearances specified here, must be
carefully observed. Other components or cables must not be installed/routed 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.
Note
When the line reactor is being installed, it is best not to install it in the same control 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
● Wiring and cabling
● Air guidance, air-conditioner
