General safety instructions
Danger:
The evaluation board works with high voltage which could be deadly for the users. Furthermore all
circuits on the board are not isolated from the line input. Due to the high power density, the
components on the board as well as the heat sink can be heated to a very high temperature,
which can cause a burning risk when touched directly. This board is intended for use by
experienced power electronics professionals who understand the precautions that must be taken
to ensure that no danger or risk may occur while operating this board.
Caution:
After the operation of the evaluation board, the bulk capacitor C1 (if used) may still store a high energy for
several minutes. So it must be first discharged before any direct touching of the board.
Important:
To protect the bulk capacitor C1, we strongly recommended using an external brake chopper after C1 (to discharge the high
brake current back from the induction motor).
