Shielding with External Shielding Busbar

Kollmorgen recommends a star point shield connection, for example, with a shielding busbar.

Shielding Concept

Example with AKD2G-Sxx--6Vxx, EMC filter and external regen resistor.

Shielding Busbar

The power cable shields (line in, motor cable, external regen resistor) can be routed to an additional busbar via shield clamps.

Kollmorgen recommends using Weidmüller KLBÜ shield clamps.

A possible scenario for setting up a busbar for the above shield clamps is described below.

 
  1. Cut a busbar of the required length from a brass rail (cross-section 10 x 3mm) and drill holes in it as indicated. All shield clamps required must fit between the drill holes.
    CAUTION: Risk of injury due to the spring force of the coil spring. Use pincers.
  2. Squeeze together the coil spring and the supporting plate and push the busbar through the opening in the holder.
  3. Mount the busbar with the shield clamps fitted on the assembly plate. Use either metal spacer bushes or screws with nuts and accessories to maintain a spacing of 50mm. Earth the busbar using a single conductor with a cross-section of at least 2.5mm².
  4. Strip the external cable sheath to a length of approx. 30mm, taking care not to damage the braided shield. Push the shield clamp up and route the cable to it via the busbar.
    NOTICE: Make sure there is good contact between the shield clamp and the braided shield.
