3.6 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.
For more information on the parameters for the cooling system and their settings,
see “Appendix G – Signal and parameter table”.
