1.3 alternator
desCrIptIon
ECO 2 and 4 pole alternators are
brushless, self-regulating and
incorporate a rotating inductor with
damper cage winding and a fixed stator
with skewed slots.
The stator windings have a shortened
pitch to reduce the harmonic content
of the output waveform.
The alternators are made in compliance
with the 98/37,73/23,89/336 CEE
directives and their amendments, and
the CEI 2-3, EN 60034-1, IEC 34-1, VDE
0530, BS4999-5000, CAN/CSA-C22.2

100·85 regulations.
Tests to verify the electromagnetic
compatibility have been carried out
in the foreseen conditions by the
standards with the neutral connected
to earth.
The robust mechanical construction
gives good access to the generator
output connections, and allows the
user to inspect the various components
with ease.
The casing is made of steel, the shields
of cast iron, and the shaft of C45 steel
and it has a keyed fan.
The mechanical protection level meets
standard IP21.
Insulation materials meet Class
H requirements, and all rotating
components are epoxy resins
impregnated; higher voltage parts,
such as the stators, are vacuum
treated.
Radio interference suppression meets
the requirements of grade "N" of VDE
0675 regulations.
The ECO alternators comply with the
EEC 98/37, 73/23, 89/336 directives
and their amendments; therefore they
pose no danger to the operator if they
are used and maintained according
to the instructions given and provided
the safety devices are kept in perfect
working conditions.
1.4 replaCement parts
Should replacement parts be required
for the alternator please contact any
Lister Petter Distributor.
When requesting parts always quote the
plant and alternator serial numbers.
Fitting Replacement Parts
Replacement parts must only be
replaced by skilled technicians with
suitable mechanical and electrical
experience.
