1.1 - Standards and safety measures Our alternators comply with most international standards and are compatible with :
- the recommendations of the
International Electrotechnical Commission
IEC 34-1, (EN 60034).
- the recommendations of the
International Standards Organisation ISO 8528.
梦随心动- the European Community directive 89/336/EEC on Electromagnetic Compatibility (EMC).
- the European Community directives 73/23/EEC and
93/68/EEC (Low Voltage Directive).
They are CE marked with regard to the LVD (Low Voltage Directive) in their role as a machine component. A declaration of incorporation can be supplied on request.
Before using your generator for the first time, read carefully the contents of this installation and maintenance manual, supplied with the machine. All operations performed on the generator should be undertaken by qualified personnel with specialist training in the commissioning, rvicing and maintenance of electrical and mechanical machinery. This maintenance manual should be retained for the whole of the machine’s life and be handed over with the contractual file. The various operations described in this manual are accompanied by recommendations or symbols to alert the ur to potential risks of accidents. It is vital that you understand and take notice of the different warning symbols.
1.2 - Inspection
On receipt of your alternator, check that it has not suffered any damage in transit. If there are obviou
s signs of knocks, contact the transporter (you may able to claim on their insurance) and after a visual check, turn the machine by hand to detect any malfunction. 1.3 - Identification
The alternator is identified by means of a nameplate fixed on the frame.
Make sure that the nameplate on the machine conforms to your order.
The machine name is defined according to various criteria (e below).
Example of description for : LSA 42.2 S4 J6/4 -
• LSA : name ud in the PARTNER range
M : Marine / C : Cogeneration / T : Telecommunications.• 42.2 : machine type
• S4 : model
• J :field excitation system
(C:AREP / J:SHUNT / 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 fill in its specifications on the nameplate below.
1.4 - Storage
Prior to commissioning, machines should be stored :
- Away from humidity : in conditions of relative humidity of more than 90%, the machine insulation can drop very rapidly, to just above zero at around 100%; monitor the state of the anti-rust protection on unpainted parts.
For storage over an extended period, the machine can be placed in a aled enclosure (heatshrunk plastic for example) with dehydrating sachets inside, away from significant and frequent variations in temperature to avoid the risk of condensation during storage.
- If the area is affected by vibration, try to reduce the effect of the vibrations by placing the generator on a damper support (rubber disc or similar) and turn the rotor a fraction of a turn once a fortnight to avoid marking the bearing rings.
