The 6SL3230-3YE46-0UF0 is the baseline unfiltered 110 kW G120X: standard coating for protected indoor environments, no integrated EMC filter, no operator panel. At 277 A in FSF frame, this is the simplest electrical configuration at the 110 kW power level — the drive handles the motor, and all filtering, control, and operator interface are external to the drive itself.

The unfiltered specification at 110 kW

An integrated EMC filter at 110 kW adds meaningful capacitance to ground through its Y-capacitors. In multi-drive installations — a pump station with four 110 kW drives on a common DC bus, or an HVAC plant room with multiple G120X units fed from one transformer — the cumulative leakage current from per-drive filters can reach levels that nuisance-trip residual-current monitors. Specifying the U (unfiltered) variant shifts EMC compliance responsibility to the system integrator but removes a source of cumulative leakage current. This is the standard engineering choice in large installations where harmonic mitigation is designed once at the bus level rather than replicated at every drive.
