8.7.2.2 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 3 mm) and drill holes
in it as indicated. All shield
clamps required must fit between
the drill holes.
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 50 mm. Earth the
busbar using a single conductor
with a cross-section of at least
2.5 mm².
4. Strip the external cable sheath
to a length of approx. 30 mm, tak-
ing care not to damage the
braided shield. Push the shield
clamp up and route the cable to it
via the busbar.
Make sure there is good con-
tact between the shield
clamp and the braided
shield.
