Cooling circuit and coolant properties
8.4 Horizontal installation
Housing for air guidance
The fan(s) can suck the air out of the module only if air cannot be sucked in between the
module and the fan. A housing (enclosure) must therefore be provided between the fan and
the module.
Motor connection cover
The motor connection on a horizontally mounted module must be covered. This cover must
be perforated. The perforations should have an opening area of 8 x 30 mm with a perforation
spacing of 3 to 5 mm (Fig. 8-12).
Fig. 8-12
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. The data must be
regarded as minimum values.
If the specified fan is not available, an alternative fan can be used provided that its
characteristic is higher than that of the minimum fan recommended. Data sheets for the
recommended minimum fan with characteristic are available on request from EBM-Papst.
