The 6SL3230-3YE20-0UP0 is the most straightforward 4 kW G120X variant: Unfiltered, no DC terminals, standard catalog ordering. It delivers 10.5 A LO at 3AC 380–480 V in the FSB frame — the baseline configuration for system integrators who provide their own EMC filtering at the cabinet level and do not need DC-link access.

When is the Unfiltered variant the right starting point?

Choosing Unfiltered gives the system integrator full control over EMC compliance strategy. Installations on IT networks (unearthed neutral) cannot use the integrated C2 or C3 filter — an external solution is mandatory. Sites with long motor cables may need output reactors or dV/dt filters that the integrated filter would duplicate. And facilities with existing cabinet-level filtering avoid paying for redundant suppression. The trade-off: the integrator must specify and install the correct external filter for the target EMC category.
