8.3.4 Connecting to a converter
8.3.4.1 Selecting and connecting the cables
• Use prefabricated MOTION-CONNECT cables from SIEMENS or shielded connecting cables.
• The prefabricated MOTION-CONNECT cables reduce installation costs and increase the
operational reliability
Note
The cable shielding, made up of as many strands as possible, must have a high electrical
conductivity. Braided shields made of copper or aluminum are well suited.
When connecting, comply with the following:
• Connect the shield to the converter.
• Keep the unshielded cable ends as short as possible.
• To ensure good discharging of high-frequency currents, provide contacting over a large
surface area.
