5.4 Notes on mounting the device version in push−through design
In case of compactly designed control cabinets, special attention has to be paid to the
dissipation of the power loss.
The device version in push−through design (E70ACxxD...) serves to separate the heatsink
losses from the other device losses and dissipate them from the control cabinet. This serves
to reduce the temperature inside the control cabinet. The thermal load of all components
is reduced and the reliability of the plant is improved.
