Arrangement of components and equipment
12.4.1
The arrangement of the components and equipment depends on the following conditions:
● Space requirements
● Cable routing
● Bending radii of the connecting cables
MOTION-CONNECT cables, refer to catalog PM21 or NC61
● Heat dissipation
● EMC
The components of the drive line-up should preferably be installed on a conductive mounting
surface to ensure low impedance between the component and the mounting surface.
Mounting plates with a galvanized surface are suitable.
Components are usually located centrally in a cabinet. The necessary mounting and
installation clearances above and below the components can possibly exceed the minimum
clearances specified in the product documentation.
The components can be arranged in one or more tiers. In a multiple-tier arrangement,
vertical mounting or, in a cabinet row, side-by-side mounting in different cabinet sections is
possible.
To determine the cross-section, the DC-link busbar current carrying capacity is used as
basis, which is specified in the relevant technical data.
A ventilation clearance of 100 mm must be maintained around the line reactor (not including
the mounting surface).
Current carrying capacity of the DC link busbar
The current carrying capacity of the DC link busbar must be observed for the configuration
and arrangement of the drive line-up. The maximum current carrying capacity of the DC link
busbar differs for the various module widths.
