NOTICE
Component damage caused by excessively low current carrying capacity of the DC link
busbars
The DC link
busbars of the individual components have different current carrying capacities.
If more current flows through a DC link busbar than is specified for it, the component will heat
up strongly and may sustain damage as a result of overheating.
● When configuring the drive lineup, carefully observe the current carrying capacities of the
individual components.
● If required, replace the DC link jumper or reduce the load.
