Selecting and connecting the power cables
• Use prefabricated MOTIONCONNECT cables from SIEMENS or shielded connecting cables.
The appropriate cables for your motor are listed in the Conguration Manual.
• The prefabricated MOTIONCONNECT 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. Protective braided copper or aluminum shield is well suited.
• Connect the protective braided shield at the converter.
• Keep the unshielded cable ends as short as possible.
• Apply the contact over a large area for a good dissipation of the high-frequency currents.
