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 - Identication 
The alternator is identied by means of a 
nameplate  xed  on  the  machine  (see 
drawing).
Make  sure  that  the  nameplate  on  the 
machine conforms to your order.
The machine name is dened according to 
various criteria, for example :
LSA 46.2 M5 C6/4 -
• LSA : name used in the PARTNER range
M : Marine
C : Cogeneration
T : Telecommunications
• 46.2 : machine type
• M5 : model
• C : excitation system
(C  :  AREP  /  J  :  SHUNT  or  PMG  /  E  : 
COMPOUND)
• 6/4 : winding number / number of poles. 
1.3.1 - Nameplate
So that you can  identify your machine 
quickly  and  accurately,  we  suggest  you 
write  its  specications  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  (section 3.2.1).  To prevent  the 
bearings  from  becoming marked,  do not 
store  in  an  environment  with  signicant 
vibration.
1.5 - Application 
These alternators are mainly designed to 
produce  electricity  in  the  context  of 
applications  involving  the  use  of 
generators.
1.6 - Contraindications to use 
Use of the machine is restricted to operating 
conditions (environment, speed, voltage, 
power, etc) compatible with the characteri-
stics indicated on the nameplate.
