Note
Install a backflush filter in the cooling circuit to prevent blockage and corrosion so that any
deposited material is flushed out.
4.1.3.3 Pressure loss
Volume flow and pressure drop in cooling circuit
Observe the nominal coolant flows specified in the following table to ensure that the motor is
cooled adequately.

Pressure equalization
If various components are connected up in the cooling circuit, it may be necessary to provide
pressure equalization.
Reactor elements are installed at the coolant outlet of the motor or the relevant components.
