hazards.
3.1 - Assembly
All mechanical handling operations
must be undertaken using suitable
equipment and the machine must be hor-
izontal. Check how much the machine
weighs before choosing the lifting tool.
During this operation, do not allow any-
one to stand under the load.
• Handling
The parts intended for lifting are largely
dimensioned and allow the manipulation of
the alternator alone. They must not be used
to lift the genset. The choice of lifting hooks
or handles should be determined by the
shape of the parts. Choose a lifting system
which respects the integrity and the
environment of the machine.
During this operation, do not allow
anyone to stand under the load.
• Double-bearing coupling
- Semi-exible coupling
Careful alignment of the machines is
recommended, checking that the lack of
concentricity and parallelism of both parts
of the coupling do not exceed 0.1 mm.
This alternator has been balanced with a
1/2 key.
• Location
The location where the alternator is placed
must be ventilated to ensure that the
ambient temperature cannot exceed 90°C.
3.2 - Checks prior to rst use
• Electrical checks
Under no circumstances should an
alternator, new or otherwise, be operated
if the insulation is less than 1 megohm
for the stator and 100,000 ohms for the
other windings.
There is possible method for restoring the
above minimum values, dry out the machine
for 24 hours in a drying oven at a temper-
ature of 110 °C.
WARNING
Ensure that the alternator has the degree
of protection matching the dened
environmental conditions.
• Mechanical checks
Before starting the machine for the rst time,
check that:
- the cooling circuit of water is done,
- all xing screws are tight, and that there are
no leaks on the water inlet and outlet,
- the length of screw and the tightening
torque are correct.

4 - SERVICING - MAINTENANCE
4.1 - Safety measures
Servicing or troubleshooting must be
carried out strictly in accordance with
instructions so as to avoid the risk of
accidents and to maintain the machine in
its original state.
All such operations performed on the
alternator should be undertaken by
personnel trained in the commissioning,
servicing and maintenance of electrical
and mechanical components, who must
wear personal protective equipment
appropriatefor mechanicalandelectrical
hazards.
Before any intervention on the machine,
ensure that it cannot be started by a manual
or automatic system and that you have
understood the operating principles of the
system.
Also check that no liquid is leaking from the
cooling circuit.
Warning : During and after running, the
alternator will reach temperatures hot
enough to cause injury, such as burns.
4.2 - Routine maintenance
• Checks after start-up
After approximately 20 hours of operation,
check that all xing screws on the machine
are still tight, plus the general state of the
machine and the various electrical
connections in the installation.
• Electrical servicing
Commercially-available volatile degreasing
agents can be used.
Do not use: trichlorethylene, perchlo-
rethylene,trichloroethane oranyalkaline
products.
These operations must be performed at a
cleaning station, equipped with a
vacuum system that collects and ushes
out the products used.
The insulating components and the
impregnation system are not at risk of
damage from solvents. Avoid letting the
cleaning product run into the slots.
Apply the product with a brush, sponging
frequently to avoid accumulation in the
housing. Dry the winding with a dry cloth. Let
any traces evaporate before reassembling
the machine.
• Mechanical servicing
Check regularly that no liquid is leaking from
the cooling circuit.
Degreasing: Use a brush and detergent
(suitable for paintwork).
Dusting: Use an air gun.
If the machine is tted with air inlet and outlet
lters, the maintenance personnel should
clean them routinely at regular intervals. In
the case of dry dust, the lter can be cleaned
using compressed air and/or replaced if it is
clogged.
After cleaning the alternator, it is essential to
check the winding insulation (see sections
3.2 and 4.5).

• Checking the winding
You can check the winding insulation by
performing a high voltage test. In this case,
you must disconnect all AVR wires.
WARNING
Damage caused to the AVR in such
conditions is not covered by our
warranty.
• Checking the windings and rotating
diodes using separate excitation
During this procedure, make sure that
the alternator is disconnected from any
external load and inspect the terminal
box to check that the connections are
fully tightened.
1) Stop the unit, disconnect and isolate the
AVR wires.
2) There are two ways of creating an
assembly with separate excitation.
Assembly A: Connect a 12 V battery in
series with a rheostat of approximately
50 ohms - 300 W and a diode on both exciter
eld wires (5+) and (6-).

SSEMBLY A
Field
Assembly B: Connect a “Variac” variable
power supply and a diode bridge on both
exciter eld wires (5+) and (6-).
Both these systems should have
characteristics which are compatible with
the eld excitation power of the machine
(see the nameplate).
3) Run the unit at its rated speed.
4) Gradually increase the exciter eld
current by adjusting the rheostat or the
variac and measure the output voltages on
L1 - L2 - L3, checking the excitation voltage
and current at no load (see the machine
nameplate or ask for the factory test report).
When the output voltage is at its rated value
and balanced within 1% for the rated
excitation level, the machine is in good
working order. The fault therefore comes
from the AVR or its associated wiring (ie.
sensing, auxiliary windings).

Disposal and recycling instructions
We are committed to limiting the
environmental impact of our activity. We
continuously monitor our production
processes, material sourcing and product
design to improve recyclability and minimise
our environmental footprint.
These instructions are for information
purposes only. It is the user’s responsibility
to comply with local legislation regarding
product disposal and recycling.
Recyclable materials
Our alternators are mainly constructed from
iron, steel and copper materials, which can
be reclaimed for recycling purposes.
These materials can be reclaimed through a
combination of manual dismantling,
mechanical separation and melting
processes. Our technical support depart-
ment can provide detailed directions on how
to dismantle products on request.
Waste & hazardous materials
The following components and materials
require special treatment and must be
separated from the alternator before the
recycling process:
- electronic materials found in the terminal
box, including the automatic voltage
regulator (198), current transformers (176),
interference suppression module and other
semi-conductors.
- diode bridge (343) and surge suppressor
(347), found on the alternator rotor.
- major plastic components, such as the
terminal box structure on some products.
These components are usually marked with
information concerning the type of plastic.
All materials listed above need special
treatment to separate waste from
reclaimable materials and should be
entrusted to specialist recycling companies.
The oil and grease from the lubrication
system should be treated as hazardous
waste and must be treated in accordance
with local legislation.
Our alternators have a specied lifetime of
20 years. After this period, the operation of
the product should be stopped, regardless
of its condition. Any further operation after
this period will be under the sole responsi-
bility of the user.
The coolant, oil and grease from the
lubrication system should be treated as
hazardous waste and must be treated in
accordance with local legislation.
