Cleaning The Cooling Air Passages; Motors With Pipe Connection - Siemens SINAMICS S 1PH7 Configuration Manual

Cleaning the cooling air passages

For air-cooled motors, the cooling ducts, through which the ambient air flows, must be
regularly cleaned depending on the degree of pollution at the mounting location. These air
ducts can be cleaned, e.g. using dry, oil-free compressed air.
Please refer to the Operating Instructions for details.

Motors with pipe connection

1PH7 motors that are configured to allow pipes to be connected and/or for operation with a
separately driven fan must have pipes and a fan of suitable type and dimensioning mounted
and connected to them.
Note
For motors with pipe/duct connection, the potential pressure drop within the motor is
specified in the table.
