Layout of the components
8.6.1
General
The arrangement of the components and equipment takes account of
● Space requirements
● Cable routing
● Bending radii of connecting cables
– For MOTION-CONNECT cables, see catalogs D21.4, D31.1 and NC62
– Hybrid cable: static 60 mm, dynamic 112.5 mm (≥7.5 · D with D = 14.6 ±0.4 mm)
● Heat dissipation
● EMC
The central components of the drive line-up should preferably be installed on a conductive
mounting surface to ensure a 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 an below the components can, under certain circumstances,
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
installation or, in a cabinet row, side-by-side installation in different cabinet sections is possible.
To determine the cross-section, use the DC link busbar current carrying capacity specified in
the relevant technical data.
A ventilation clearance of 100 mm must be maintained around the line reactor (not including the
mounting surface).
8.6.2
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.
