Extending a PROFIBUS DP line with a 160 kW pump is straightforward engineering until the EMC review asks which grid the supply shares. The 1AP0 build of this SINAMICS G120X has the answer built in: the C2 filter class for networks that also serve non-industrial premises, the DP interface that joins the existing master as a slave, and the DC terminals for the du/dt filter if the cable run demands it.

Where does a 160 kW C2 build typically land?

On the mid-tier of shared-infrastructure sites: university energy centres, hospital utility wings, campus pump rooms — loads heavy enough to justify the FSG frame, on grids regulated tighter than a pure industrial second environment. The integrated C2 filter meets those first-environment limits without an external filter stage, so the DP extension passes review on the strength of the build itself rather than added hardware.

What stays constant across the 2YE50 order numbers?

The power stage and the frame. Every 160 kW build rates 302 A in LO duty (110% per 60 s, 160 kW continuous) against the 408 A maximum, runs 132 kW in HO duty, and mounts in the 305 x 999 x 369 mm FSG housing with the integrated DC link reactor. The ordering letters — DC terminals, filter class, fieldbus — describe the installation, so the engineer reads them off the site survey rather than from a power calculation the family has already answered.
