System role

This section explains what the product does and where it acts in the surrounding system.

Function: The component controls the inrush current while the SINAMICS DC link is precharged.
System position: It sits between the AC-side precharging circuit and the SINAMICS DC link.
Upstream / inputs: It receives the initial charging current from the AC-side precharging circuit.
Downstream / outputs: It delivers a limited charging current to the SINAMICS DC link.
Limitations: Unknown: installed wiring, configuration, firmware compatibility, and current unit condition.
