Safety precautions

I Exhaust gas

Exhaust gases contain carbon monoxide. This colour­less and odourless gas is extremely harmful and could
lead to poisoning which could result in loss of conscious­ness or death. The rst symptoms of carbon monoxide
intoxication are as follows:

• Dizziness

• Nausea

• Headache

• Throbbing temples

• Vomiting

• Fatigue and falling asleep

• Tense muscles

If you or anyone else in the vicinity of the generating set
experiences any of these symptoms, leave the area of
operation of the generating set and nd fresh air. If the
symptoms persist, consult a doctor and have your gen­erating set checked.

I Risk of electric shock

Never touch the electrical connectors when the gener­ating set is operational. The voltage at the connector
terminals can be lethal.

Do not work on the generating set without protection:
protective goggles and gloves, insulating blankets etc.

Always disconnect the generating set and cut the cur­rent before working on the electrical system. Isolate the
shore power supply to all the electrical circuit equip­ment.

Ensure your clothing and skin is not damp or sweaty
when handling electrical equipment. Remove watch­es, bracelets and jewellery when working on electrical
equipment.

Handling a capacitor that is still charged can be danger­ous and cause electrocution.

I Risk of burns

Never touch the hot parts of the generating set or the
exhaust circuit.

An operational generating set gets very hot: the exhaust
elbow and pipe, turbocompressor, starter, oil sump, oil,
coolant in the hoses and pipes are hot and can burn.

Always check the coolant level before starting the gen­erating set.

Fluids ejected under pressure can cause serious injury.

Release all the pressure in the circuits before removing
the caps.

Never open the coolant and oil circuit caps when the
generating set is operational and/or hot.

Never start or run the generating set when the oil ll cap
is not screwed on as hot oil could spray out.

If you come into contact with any of these uids, consult
a doctor immediately.

If the generating set gets too hot, switch it off and dis­connect it and wait for it to cool down before handling.

I Risk of re

Do not smoke near the generating set and keep it away
from sources of ignition (ames or sparks) or any other
potential ammable vapour or liquid sources.

Do not run the generating set without an air lter.

Do not run the generating set in an area in which am­mable or explosive materials are stored or where gas is
present. Ensure there are no ammable liquids in the
engine compartment.

Immediately clean up any liquids spilled over yourself or
the oor and keep the engine compartment clean and
accessible so as to minimise the risk of re. Be careful
as fuel can burn.

I Risk of explosion

Explosions caused by fuel vapour can cause serious
injury! Carefully follow the safety rules when lling the
fuel.

Open and ventilate the storage area of the generating
set after lling. Check that there are no fuel vapours or
leaks before starting the fan (if tted). Switch the fan on
for 5 minutes before starting the generating set.

All fuel vapours are ammable and explosive. Be care­ful when handling and storing fuel. Store the fuel in a
ventilated area away from sources of ignition (sparks or
ames) and out of the reach of children.

Stop the generating set before lling with fuel or lubri­cant. Do not smoke near the generating set and keep it
away from sources of ignition (ames) when lling with
fuel and/or lubricant. Wear gloves when investigating
possible leaks.

Do not alter or damage the fuel circuit. Close the fuel
circuit whenever you work on it.

Ensure you always have an appropriate working extin­guisher to hand.

Safety precautions

I Accidental starting

Accidental starting can cause serious injury and even
death!

Disconnect the battery before working on the generat­ing set.

Ensure no one is alongside the generating set or work­ing on the set before starting it.

Ensure all the protection mechanisms are in place be­fore starting the generating set.

I Risk of battery explosion

A battery explosion can cause serious injury and even
death!

Do not smoke near the batteries and keep them away
from sources of ignition (ames or sparks). They pro­duce hydrogen which could ignite or explode on contact
with an electrical arc or a ame. Switch off all electrical
appliances in the vicinity when you are working on the
batteries. Ensure the battery storage compartment is
corrected ventilated.

Avoid touching the battery terminals with metal tools so
that no sparks are created which could cause an ex­plosion. Remove your rings, bracelets and necklaces
before handing the batteries.

I Battery acid

The acid in batteries can cause serious injury and even
death!

When servicing the batteries, wear protective gloves
and goggles. Batteries contain sulphuric acid which is
highly corrosive.

Acid can spurt from batteries when they are handled.
If the acid comes into contact with the skin, rinse thor­oughly in fresh water and consult a doctor.

I Exhaust gas

Ensure the exhaust circuit correctly expels the gas pro­duced by the generating set.

Regularly check that the exhaust circuit is free of leaks
and that the exhaust elbow is correctly afxed.

Operate the generating set in a well aerated and ven­tilated area away from other people. Run the fan when
the generating set is operational.

Do not wear bracelets, necklaces or rings when working
on a generating set.

Check that the bolts and screws are properly tightened
and that the protection mechanisms are in place.

Do not check the uid levels or tension of the alternator
belt when the generating set is operational.

I Lifting the generating set

To lift the generating set, use the hoisting eyes on the
appliance.

Always check the robustness and overall condition of
the lifting equipment. Use suitable gear (cables, beams,
machines, etc.) to lift your generating set. Check that
your gear is capable of lifting the set.

Lifting cables and chains must be able to move parallel
to each other.

Do not forget that any additional equipment mounted on
the generating set could alter its centre of gravity. When
lifting the set, it should remain as parallel as possible to
the ground.

I Maintenance and spare parts

Nanni Diesel engines are designed to meet the different
emission standards while delivering maximum service
life and reliability.

Regularly servicing and replacing parts with original
Nanni Diesel parts will ensure the generating set con­tinues to function optimally.

These parts can be ordered from all Nanni Diesel deal­ers throughout the world.

I Chemical products

The different uids used to run the generating set are a
health hazard.

Carefully read the instructions on the packaging of
these products and always check that the ventilation in
the hold space is adequate.

I Rotating parts

Rotating parts can be extremely dangerous and cause
serious injury and even death!

Do not work on the generating set when it is operational.
If work on the engine when running is absolutely neces­sary, do not touch any hot or rotating parts.

Baggy clothing, hair or objects could be pulled in and/or
caught and cause serious injury or substantial property
damage.

Identification numbers

Your generating set has 2 identication plates: one for
the engine and one for the generator.

Keep these plates accessible and in good condition.
Record and keep the engine and generator serial
number and designation. These numbers will be useful
if you work on your set, order parts or invoke the war­ranty.

The engine identication plate is as follows:

Checks before commissioning

I Caution! : Your generating set must be installed by a
shipyard or authorised representative following the on­board assembly instructions.

The electrical connections must also be carried out by
qualied personnel. The electrical installation must be
equipped with all the mechanisms for protecting people
and property in accordance with the applicable stand­ards.

When the set has been installed on board and before
removing the protective elements covering the different
orices, clean the exterior surface of the generating set.

For transportation reasons, some of our generating
sets are delivered without their operating uids. In all
cases, you must:

• Check the levels and ll the engine oil if necessary.

• Fill the exchanger with coolant and degas if neces­sary.

• If necessary prime the raw water circuit

• Check the belt tension.

• The TYP inscription indicates the commercial des­ignation of the generating set (eg. QMS10T).

• The NR inscription indicates the engine serial
number.

• The CODE inscription lists the various specica­tions of your engine.

The elements on the alternator identication plate are
explained in the alternator documentation.

About the generator

Refer to your generator manual for more information
about this component.

The generators are installed and run for the rst time in
our factory. A professional electrician should connect
the generating set to the craft’s electrical circuit follow­ing the applicable safety standards.

Always check the installation of your generating set be­fore handling it. Check the overall condition of the gen­erator, the tightness of the assembly screws and the
stability of the generator as a whole.

• Check the tightness of the different connections
and drain caps (coolant and oil).

• Check the tightness of the alternator electrical lugs
(check the cabling by referring to the corresponding
documentation), battery terminals, circuit breaker,
connection of extension sections, battery electro­lyte level.

• Make a nal check of the xing elements and a vis­ual check of the generating set as a whole.

Some of these operations are explained in more detail
later in this manual.

I Caution! : The modern fuel engine is precision
equipment that requires the use of a high-quality fuel
and lubricant.
