G0637/G0638 Cyclone Dust Collector
-35-
Always guard against
static electrical build up
by grounding all dust
collection lines.
We also recommend wrapping the outside of all
plastic ducts with bare copper wire to ground the
outside of the system against static electrical build
up. Wire connections at Y’s and T’s should be
made with wire nuts.
Attach the bare ground wire to each stationary
woodworking machine and attach to the dust
collector frame with a ground screw as shown in
Figure 59. Ensure that each machine is continu-
ously grounded to the grounding terminal in your
electric service panel.
Ensure that the entire system is grounded. If using
plastic blast gates to direct air flow, the grounding
wire must be jumped (
Figure 58) around the
blast gate without interruption to the grounding
system.
