Note
Notes for installation in control cabinets
The SINAMICS S120 water-cooled devices have IP20 degree of protection with the
exception of the electrical connections (overall degree of protection IP00).
Depending on the degree of protection of the cabinet, it must be guaranteed that the thermal
losses in the cabinet are extracted from the cabinet using a fan or an air/water heat
exchanger.
the respective thermal losses can be found in the technical data of each individual device.
We recommend that a heat run is performed in order to be able to maintain the temperature
ranges specified in the technical data also when installed in a cabinet.
Horizontal installation
The following table lists the fans required for different module types and also specifies the
volumetric flow which must be provided through the SINAMICS device. These are minimum
values, without taking into account additional components in the cabinet (e.g. fuses, busbars,
etc.). The additional power losses must be taken into account.
If the specified fan is not available, an alternative fan can be used provided that its
characteristic is higher than that of the fan recommended (fan with higher air flow rate). Data
sheets for the recommended fan with characteristic (minimum requirement) are available on
request from EBM-Papst.

Note
Note regarding horizontal installation
If the measures recommended above are not implemented, the equipment might malfunction
during operation at air temperatures as low as approx. 30° C. This is because the current
transformers would be overheated!
