Dukane Manual Part No. 403–566–01
Section 2 – Safety Tips
The power cable normally provided for interna-
tional use is compatible with many power outlets
(refer to Figure 2-3.) However, if your applica-
tion requires another type of cable, check with
the local Dukane products representative, and fol-
low local regulations concerning proper wiring
and grounding.
RFI Considerations
In addition to the safety considerations, proper
grounding at the generator power cord is essen-
tial for the effective suppression of RFI (Radio
Frequency Interference). Every DPC contains a
RFI filter which blocks noise on the AC power
line from entering the DPC control circuitry. This
filter also prevents ultrasonic RFI from being fed
back into the AC power line. In order for the RFI
filter to operate properly, it is necessary to ad-
equately ground the DPC. Run an additional
grounding wire from the rear grounding connec-
tion (see Figure 2-4) to the nearest grounded metal
pipe or equivalent earth ground by means of a
ground clamp. Use at least an 14 AWG** wire
for the connection to the DPC chassis. Stranded
is more flexible and easier to work with than solid
wire. However if you use stranded wire, crimp
spade lugs on the end to ensure a good connection.
If you have a color choice, green is the commonly
accepted color for an electrical ground connection.
If you have connected the DPC to a Press and/or
Thruster, use a star

Run seperate ground wires from each piece of
equipment to the earth ground. See the appropri-
ate schematic diagram in Figures 3–4 thru 3–8.
