Connection Cross-Sections and Cable Lengths

Connection Cross-Sections
The connection cross-sections for the input power connection, motor connection,
and cabinet grounding for your cabinet unit are specified in the tables provided in
the "Technical Data" section.
Cable Lengths
The following table shows the maximum permissible cable lengths (with output filter
(option L08) and without output filter) for standard cable types or cable types
recommended by SIEMENS. Longer cables can only be used after consultation.
The cable lengths specified represent the actual distance between the cabinet unit
and the motor, taking into account parallel routing, current-carrying capacity, and
the cable-laying factor.
