5 - the European Community directives73/23/EEC and 93/68/EEC (Low Voltage Directive)They are CE marked with regard to the LVD (Low VoltageDirective) in their role as a machine component. A declarationof incorporation can be supplied on using your generator for the first time, read carefullythe contents of this installation and maintenance manual,supplied with the machine. All operations performed on thegenerator should be undertaken by qualified personneltrained in the commissioning, servicing and maintenance ofelectrical and mechanical components.

6 This maintenancemanual should be retained for the whole of the machine's lifeand be handed over with the contractual various operations described in this manual areaccompanied by recommendations or symbols to alert theuser to the potential risk of accidents. It is vital that youunderstand and take notice of the different warning - InspectionOn receipt of your alternator, check that it has not sufferedany damage in transit. If there are obvious signs of knocks,contact the transporter (you may be able to claim on theirinsurance) and after a visual check, turn the machine by handto detect any malfunction.

7 - IdentificationThe alternator is identified by means of a nameplate glued tothe sure that the nameplate on the machine conforms toyour machine name is defined according to various criteria(see below).Example of description: LSA 36 L7 G6/2 LSA: name used in the PARTNER range 36 : Machine type L7: Model G:Excitation system: COMPOUND 6/2: Winding number/number of - NameplateSo that you can identify your machine quickly and accurately,we suggest you write its specifications on the nameplatebelow. - StoragePrior to commissioning, machines should not be stored inhumid conditions: at relative humidity levels greater than90%, the machine insulation can drop very rapidly, to justabove zero at around 100%.

8 The state of the anti-rustprotection on unpainted parts should be storage over an extended period, the machine can beplaced in a sealed enclosure (heatshrunk plastic for example)with dehydrating sachets inside, away from significant andfrequent variations in temperature to avoid the risk ofcondensation during the area is affected by vibration, try to reduce the effect ofthese vibrations by placing the generator on a dampersupport (rubber disc or similar) and turn the rotor a fraction ofa turn once a fortnight to avoid marking the bearing ALTERNATORSLSA Date N Hz Min-1 Protection Altit.
