b.
Grounding. Ensure generator sets are grounded to GROUND TERMINAL studs, two each, on trailer body. Using
ground wire supplied, connect each of the power plant's two ground studs to a suitable ground as described below. The
following sources of a good ground are listed in order of preference.
NOTE
As a substitute for the supplied ground wire, any copper wire of at least No. 6 AWG may be
used.
(1)
Underground water system. Ground power plants to one of the accessible pipes in an underground water
system. Make certain underground pipe is made of metal and there is no insulation, such as a water
meter, between ground wire and earth.
(2)
Ground rod. Drive ground rod a minimum of 8 feet into earth. A ground rod must have a minimum
diameter of 5/8-inch if solid, or 3/4-inch if pipe.
NOTE
It may be necessary to saturate the area around ground rod with water if soil conditions are dry.
c.
External Fuel Line Connection. (See Figure 4-2). The power plant generator sets can be fueled from an external
source such as a 5-gallon fuel can or 55-gallon drum. This eliminates the need for frequent refilling of each generator's
fuel tank during long intervals of operation.
(1)
Remove fuel can adapter and fuel pickup tube from storage locations on power plants and assemble by
threading pickup tube into adapter.
(2)
Thread one end of auxiliary fuel line onto fuel can adapter fitting and tighten.
(3)
Connect free end of auxiliary fuel line to AUXILIARY FUEL CONNECTION. This connection is located
directly to the left of the fuel drain on the left-hand side of generator set.
(4)
Insert fuel can adapter in external fuel source and secure by pressing down on lever.
(5)
Set MASTER SWITCH on control panel to RUN AUX FUEL position.
