7.3 Horizontal installation
Volumetric air flow and fans required
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 fan recommended (fan with higher air flow rate). Data
sheets for the recommended minimum fan with characteristic are available on request from
EBM-Papst.

NOTICE
If the measures recommended above are not implemented, the equipment might
malfunction in operation at air temperatures as low as approx. 30 °C. This is because the
current transformers would be overheated!
Coolant connection
The coolant connection must be designed to prevent any coolant leakage into the unit. It is
advisable to empty the coolant hoses before connecting them and to plug the heat sink
before removing the coolant hoses.
