Layout of the components
8.5.1
General information
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 D21.4 or
NC62)
• EMC
The components of the drive lineup 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 ventilation clearances required above
and below the components can possibly exceed the minimum clearances specified in the
manual.
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.
The DC link busbar current-carrying capacity, which is specified in the relevant technical data, is
used to determine the cross-section. You must maintain a ventilation clearance of 100 mm
around the line reactor (not including the mounting surface).

DC link busbar current-carrying capacity
Carefully observe the current-carrying capacity of the DC link busbar when engineering and
installing the drive lineup. The maximum current-carrying capacity of the DC link busbar differs
for the components.
