9.7.2.2 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.
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 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, taking 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.
