WARNING
! Never lift the generating set by attaching to the engine or
alternator lifting lugs.
! Ensure the lifting rigging and supporting structure is in good
condition and is suitably rated.
! Keep all personnel away from the generating set when it is
suspended.
! If the generating set is going to be lifted, it should be lifted by
the lifting points fitted on canopied sets and most open sets.
5.4 LOCATION
Selecting a location for the generating set can be the most important
part of any installation procedure. The following factors are important
in determining the location:
• Adequate ventilation.
• Protection from the elements such as rain, snow, sleet, wind
driven precipitation, flood water, direct sunlight, freezing
temperatures. or excessive heat.
• Protection from exposure to airborne contaminants such as
abrasive or conductive dust, lint, smoke, oil mist, vapors, engine
exhaust fumes or other contaminants.
• Floor of generating set room must be smooth and strong.
Protection from impact from falling objects such as trees or
poles, or from motor vehicles or lift trucks.
• Clearance around the generating set for cooling and access for
service: at least 1 meter (3.3 feet) around the set and at least
2 meters (6.6 feet) headroom above the set.
• Access to move the entire generating set into the room. Air
inlet and outlet vents can often be made removeble to provide
an access point.
• Limited access to unauthorized personnel.
If it is necessary to locate the generating set outside of the
building, the generating set should be enclosed in a canopy.
A canopy is also useful for temporary installations inside or
outside the building.
5.5. FOUNDATION’S VIBRATION ISOLATION
The generating set is shipped assembled on a rigid baseframe that
precisely aligns the alternator and engine and needs to be bolted
down only to a suitably prepared surface.
Foundation
A reinforced concrete pad provides a rigid support to prevent
deflection and vibration. Typically the foundation should be 150
mm (6 inches) deep and at least as wide and long as the generating
set. The ground or floor below the foundation should be properly
prepared and should be structurally suited to carry the weight of
the foundation pad and the generating set.
(If the generating set is to be installed above the ground floor the
building structure must be able to support the weight of the
generating set, fuel storage and accessories). If the floor may be
wet from time to time such as in a boiler room, the pad should be
raised above the floor. This will provide a dry footing for the
generating set and for those who connect, service or operate it.
It will also minimize corrosive action on the baseframe.
5.6. COMBUSTION AIR INLET
Air for engine combustion must be clean and as cool as possible.
Normally this air can be drawn from the area surrounding the
generating set via the engine mounted air filter. However, in some
cases due to dust, dirt, or heat, the air around the set is unsuitable.
In these cases an inlet duct should be fitted. This duct should run
from the source of clean air (outside the building, another room,
etc.) to the engine mounted air filter. Do not remove the air filter
and mount it at a remote location as this can increase the possibility
of dirt leaking through the ductwork and into the engine inlet.
5.7. COOLING AND VENTILATION
The engine, alternator, and exhaust piping radiate heat which can
result in a temperature high enough to adversely affect the
performance of the generating set. It is therefore important that
adequate ventilation is provided to keep the engine and alternator
cool. Proper air flow, as shown in Figure 5.4, requires that the air
comes in at the alternator end of the set, passes over the engine,
through the radiator and out of the room via a flexible exhaust
duct. Without the ducting of the hot air outside the room, the fan
will tend to draw that hot air around and back through the radiator,
reducing the cooling effectiveness.
