Shielding Busbar
The power cable shields (line in, motor cable, external regen resistor) can be routed to an additional
busbar via shield clamps. Emerson recommends using shield clamps. A possible scenario for setting
up a busbar for the above shield clamps is described below.
Figure 27: Shielding Bus Bar
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.
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, taking care not to damage the
braided shield. Push the shield clamp up and route the cable to it via the bus- bar.
