Connecting 1 Psm 510 To The Ac Choke; Connecting 2 Psm 510 Modules To The Ac Choke - Danfoss VLT ISD 510 Operating Manual

VLT® Servo Drive System ISD 510/DSD 510
Operating Guide
If 2 PSM 510 modules are installed in parallel, use an AC choke as specified in
to the AC Choke for further information.
Table 24: Line Choke Characteristics for 2 PSM 510 installed in parallel
Model
PSM 510 (2 x 30 kW)
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.

5.10.1.2 Connecting 2 PSM 510 Modules to the AC Choke

Connect the PSM 510 modules to the same AC choke as shown in
Ensure the choke used is the correct size based on the combined power of the PSM 510 modules.
When 2 PSM 510 modules are used, the wiring between the AC line choke and each PSM 510 must be the same length within a
tolerance of 0.5 m.
Connect each PSM 510 to the AC choke directly. Parallel wiring is not permitted.
