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 is achieved in two ways:
■ The cabinet design consists of folded, galvanized sheet metal plates
(the thickness is approximately 2 mm). The space between the rivets
is minimized.
■ The inside walls are not painted, because paint tends to reduce the
effectiveness of metallic bonding which is important to successful
EMC. Only the front of the cabinet is painted, all other walls are
galvanized.
