Connecting the DC Power
The Power stage of the Eagle is fully isolated from other sections of the Eagle, such as the control
stage and the heat sink. This contributes very significantly to the safety and the EMI immunity of
the Eagle. In addition it simplifies the requirements of the DC power supply used to power the DC
bus of the Eagle and allows also the operation with a non-isolated DC power source.

In this case, the isolation is achieved by the isolation transformer. It is highly recommended to
connect the network PE to the Return (negative terminal) of the Power Supply.
