1 - RECEIPT
1.1 - Standards and safety
measures
Our alternators comply with most
international standards.
See the EC Declaration of Incorporation on
the last page.
1.2 - Inspection
On receipt of your alternator, check that it
has not suffered any damage in transit. If
there are obvious signs of knocks, contact
the transporter (you may be able to claim
on their insurance) and after a visual
check, turn the machine by hand to detect
any malfunction.
1.3 - Identication
The alternator is identied by means of a
nameplate xed on the machine (see
drawing).
Make sure that the nameplate on the
machine conforms to your order.
So that you can identify your alternator
quickly and accurately, we suggest you ll in
its specications on the nameplate below.
1.4 - Storage
Prior to commissioning, machines should
be stored:
- away from humidity (< 90%); after a long
period of storage, check the machine
insulation. To prevent the bearings from
becoming marked, do not store in an
environment with signicant vibration.
1.5 - Application
This alternator is mainly designed to
produce electricity in the context of
applications involving the use of
generators.
1.6 - Usage restrictions
Use of the machine is restricted to operating
conditions (environment, speed, voltage,
power, etc) compatible with the characteri-
stics indicated on the nameplate.

permanent magnets, wound as ”full pitch”,
12-wire, with class H insulation.
- 4 PT 1000 stator temperature detection
sensors connected to a fast-on connector.
2.2 - Mechanical characteristics
- Steel frame
- Steel DE and NDE shields
- Regreasable insulated ball bearings
- Double-bearing with SAE ange and
standard cylindrical shaft extension
- Water-cooled enclosed machine
- Degree of protection: IP 69
3 - INSTALLATION
Personnel undertaking the various
operations indicated in this section must
wear personal protective equipment
appropriate for mechanical and electrical
hazards.
3.1 - Assembly
All mechanical handling operations
must be undertaken using suitable
equipment and the machine must be ho-
rizontal. Check how much the machine
weighs before choosing the lifting tool.
During this operation, do not allow
anyone to stand under the load.
• Handling
The generously-sized lifting eyes are for
handling the alternator only. They must not
be used to lift the genset. The choice of
lifting hooks or handles should be
determined by the shape of the lifting eyes.
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 room where the alternator is placed
must be ventilated to ensure that the ambient
temperature cannot exceed the data on the
nameplate.
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.
