8.4.2.2 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-sec-
tion 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 bus-
bar 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 bus-
bar.
Make sure there is good contact
between the shield clamp and the
braided shield.
