Low Voltage Alternators - 4 pole
3 -INSTALLATION
Personnel undertaking the various
operations indicated in this section must
wear persona! protective equipment
appropriateformechanical and electrical
hazards.
3.1 -Assembly
Ali mechanical handling operations
must be undertaken using suitable
equipment and the machine must be
horizontal. Check howmuch 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.

The TAL A44 is equipped with two air
deflectors that prevent access to the upper
and lower holes of the flange. Coupling for
this machine should be done with bolts in
the eight accessible holes, disregarding the
ones that cannot be accessed because of
the deflectors.

Before coupling, check the compatibility
between the alternator and the engine by
performing:
- undertaking a torsional analysis of the
transmission (alternators data are available
on request),
- checking the dimensions of the flywheel
and its housing, the flange, coupling dises
and offset.
• Double-bearing coupling
- Semi-flexible 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.
