3 INSTALLATION
3.1 G
ENERAL
INSTALLATION
CRITERIA
The installation of one or more Generating Sets must be
designed by specialised engineers qualified for the
design of this type of plant. The installation must be
carried out by qualified organisations employing
specialised personnel and using suitable equipment.
The systems must be installed in workmanlike manner
and upon completion the installer must issue the client
with a Declaration of Conformity of the systems installed
in accordance with the design specifications and the
specific standards.
3.2 I
MPORTANT
INFORMATIONS
3.2.1 I
NSPECTION
OF
MATERIALS
On receiving the set, it is advisable to check that the
materials correspond to that listed on the delivery note
accompanying the shipment. Some of the packages
may be opened at random to check that no damage has
occurred during transit. If damage is noted, the carrier
must be informed immediately to enable the relevant
claims procedure to be started.
3.2.2 S
AFETY
STANDARDS
FOR
DIESEL
ENGINES
The location and installation of the generating set
(foundations, fuel tank, air intake, gas exhaust) must
comply with the “Safety Standards” in force in the
country of installation.
3.2.3 F
OUNDATIONS
The foundations must be calculated and designed by
civil engineers, taking maximum care to avoid the
transmission of vibrations and noise to other parts of the
structure.
3.3 E
XHAUST
PLANT
3.3.1 E
XHAUST
PIPE
The exhaust pipe must convey the exhaust gas to a zone
where it will not cause damage or harm, and away from
doors, windows and air intakes.
The outlet must be provided with a fixed protection to
prevent the ingress of rainwater.
Sections of pipes passing through walls must be insulated
to prevent the transmission of heat to the walls
themselves.
3.3.2 E
XHAUST
PIPE
DESIGN
The back pressure on the engine exhaust greatly influences
the power delivered by the engine and its thermal load.
Any excessive back pressure (measured on the outlet side
of the exhaust manifold for induction engines and on the
turbine outlet side for turbocharged engines) causes a
decrease in power, an increase in the temperature of the
exhaust gases, produces smoke, increases fuel consumption
and superheats the cooling water, with subsequent
deterioration in the lubricant and consequences for other
engine parts.
The pipelines should be as short as possible and with a
minimun number of bends.
3.4 V
ENTILATION
Ventilation of the room in which the generating set is installed
is of fundamental importance for the proper operation of the
set itself (

PAR
. 3.8).
3.5 F
UEL
SYSTEM
The standard Generating Sets normally supplied by
ma
s
e
are fitted with a complete fuel system from the engine to the
standard fuel tank incorporated.
3.6 E
LECTRICAL
CONNECTION
The electrical connection must be carried out exclusively by
a specialised technician according to EN 60 204.1 (IEC
204.01) regulations.
The generating sets are supplied already set-up for connection
to the user.
The function of the generating set is to substitute the mains
electricity supply, and as such, must be considered as an
external source of energy. In the execution of the connections
must be respected the suitable connections in the wiring
diagram furnished with the group.
3.6.1 P
OWER
CABLES
SIZES
The choice and size of cables to use is the responsibility
of the plant installer.
It should be emphasised that using smaller sections
than that recommended would cause excessive voltage
drops and lead to dangerous overheating of cables.
