HD output chokes

  • Install the output choke close to MOVITRAC® B beyond the minimum clearance.
  • Always route all 3 phases (not PE!) through the output choke.
  • If the cable is shielded, the shield should not be routed through the output choke.
  • In the case of the HD output choke, the cable must be wrapped around the choke 5 times.

Only 5 loops are possible if the cable has a large diameter. To make up for this, 2 or 3 output chokes should be connected in series. SEW-EURODRIVE recommends connecting in series 2 output chokes in case of 4 windings, and 3 output chokes in case of 3 windings.

 

  • Installing HD012 output chokes:
  • Install the output choke under the respective inverter. Leave a ventilation space of at least 100 mm (3.94 in) below and above the output choke. Provide a clearance of 10 mm (0.39 in) on each side.
  • Three alternative connection options are provided for connecting the protective earth. You can connect the PE line of the motor cable directly to the frequency inverter.
