Cabinet configuration and shielding

The cabinet configuration image below is intended to help the user become familiar with

EMC-critical parts. This example does not claim to show all possible cabinet components or

configuration options.

Later figures show details that are not made immediately clear by the overview image and

which may also have an effect on the cabinet's resistance/interference emission levels, as

well as shield connection techniques.

Arrangement of RFI suppression filters and line reactors

Another section shows how the RFI suppression filters and line reactors are arranged in a

SINAMICS DC MASTER. The order in which the reactors and filters are installed must be

adhered to. The filter cables on the line side and modular side must be physically separated.

For information on selecting fuses for semiconductor protection, please refer to the section

titled "Fuses".
