Outdoor Installation
Install the generator in a location where it will not be
exposed to rain or sunshine. Make sure the generator is
on secure level ground so that it cannot slide or shift around.
Also install the generator in a manner so the exhaust will
not be discharged in the direction of nearby homes.
The installation site must be free from excessive moisture
and dust. All electrical equipment must be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and
grounding.
Foreign materials such as dust, sand, lint and abrasive
materials will cause excessive wear to the engine and
alternator parts.
CAUTION :
Pay close attention to ventilation when
operating the generator inside tunnels and
caves. The engine exhaust contains
noxious elements. Engine exhaust must
be routed to a ventilated area.
Indoor Installation
Exhaust gases from diesel engines are extremely
poisonous. If the generator is installed indoors, the exhaust
fumes must be vented to the outside. The engine must be
installed at least two feet from any outside wall. Using an
exhaust pipe that is too long or too small will cause
excessive back pressure resulting in engine overheating.
Eliminate the danger of deadly carbon monoxide gas.
Exhaust fumes from any diesel engine are very poisonous
if discharged in a closed room, but harmless if allowed to
mix with the outside air.
CAUTION :
An electric shock will happen when
vibrators are used. Pay close attention to
handling when operating vibrators and
always use rubber boots and gloves to
insulate the body from electrical shock.
Generator Grounding
To prevent electrical shock and possible damage to the
equipment, it is important to provide a good EARTH ground.
Article 250 (Grounding) of the National Electrical Code (NEC)
provides guide lines for proper grounding and specifies the
cable ground shall be connected to the grounding system of
the building as close to the point of cable entry as practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm
2
) or larger.
b. Aluminum - 8 AWG (8.4 mm
2
) or larger.
2. When grounding the generator (Figure 27) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the other
end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.

NOTE
When connecting the generator
to any buildings electrical system
ALWAYS consult with a licensed
electrician.
