Multiple-tier configuration
Figure 7-6
Note
When the power supply input is on the right-hand side of the drive line-up (e.g. in a multiple-
tier configuration), the above rules apply in reverse. This means that the Motor Modules are
arranged in order of power from the highest power to the lowest power followed by the DC
link components, such as the Braking Module.
In the case of Active Line Modules as of 55 kW, the Motor Modules can be mounted on the
right or left (see "DC link adapter").
