The configuration and dimensions of the braking resistors depend on the specific
application.
For information, see the “Dimensioning of braking resistors” application note.

3.5. Cabinet design
The riveted and folded cabinet construction of the drive ensures a strong, flexible
and self-supporting framework. The construction avoids the need for additional
skeletal support and provides effective protection against electromagnetic
emissions.
EMC has been achieved by applying a cabinet design consisting of folded,
galvanized sheet metal plates (approximately 2 mm thick) and minimizing the
space between the rivets. The inside walls of the cabinet are not painted, because
paint tends to reduce the effectiveness of metallic bonding which is important for
successful EMC.
Accordingly, only the front of the cabinet is painted while all other walls are
galvanized. However, the cabinet can be ordered optionally with the whole of the
outside painted. EMC performance is further enhanced by the use of metal cable
ducts.
