Danfoss recommends mounting the AC line choke close to the PSM 510.
The maximum cable length depends on the cross-section, and the required voltage and current at the DC-link.
If the AC line chokes are mounted away from the PSM 510, the maximum cable distance is 5 m.
5.9.1.1 Connecting 1 PSM 510 to the AC Choke
Connect the PSM 510 to the electric grid with the correct AC choke for the power size of the PSM 510.
