2.1.4 Center infeed (single row construction) for 55/80/120 kW Line Module
Another variant of the DC link supply is the center infeed. For the 55 / 80 / 120 kW Line
Modules, the DC link can be fed from both the left- and right-hand side of the device. This
allows the drive group to be mounted on both sides. The installation guidelines are the same
as the previous guidelines.
