Generator Voltages and Schematic
17-83. Generator sets should be located in easy-to-
clean, dry areas. When installed outdoors, the set
should be a housed unit, or an enclosure should be built
to protect it from inclement weather. Don't overlook the
possibility of spring flooding or high water level during
storms if the set is to be located in a low area such as a
water front or basement installation.
17-84. Screens or other protection should be provided
to safeguard against potential fire hazards and/or
operational problems which can be caused by rodents,
insects, birds, etc. They have been known to live or
17-85. Whenever possible, install the set in an area
which can be quickly reached for repair in case of
malfunction. Service entrances should be large enough
to permit removal of large components such as engine,
radiator, or generator in the even major overhaul or
replacement becomes a necessity.
17-86. Service items that are hard to reach will not be
properly maintained. Make sure ample room is provided
around the set especially at points requiring regular
attention. Figure 17-25 illustrates the location of items
requiring regular service. An item requiring daily
attention must, of course, be made more accessible
than one requiring service every 5000 hours.
For standby units it is important that servicing is
performed on a calendar basis since it may take
years to accumulate any significant number of
hours to the set. Failure to do this may result in
the set not starting or operating properly when
the unit is most needed.
17-87. Before initial startup, refer to the installation
check list, table 17-10 to ensure that the generator set is
Connect battery just prior to starting set. Be sure
connections are tight and polarity is correct. (Check
wiring diagram. ) All 500 KW DOD generator sets are
designed for negative ground. Make certain muffler is
installed with proper air flow. Inlet and outlet
connections must be made as labeled on the muffler.
