A drop in cooling air fl ow or inadequate
protection of the gen er a tor can lead
to damage and/or malfunction of the
windings.
WARNING!
canopy should be designed so that there is a minimum
clearance of 50mm between the generator air vent and
any flat surface.
The space around the air exit protection grid must be
free.
The generator's rotor is dynamically balanced in factory.
The engine induces quite complex vibrations, including
harmonics with different frequency that, when added to
the generator vibrations, can cause substantial vibration
levels dangerous for the generating set operation.
Therefore it is es sen tial that the plant engineer takes all
necessary measures to ensure align ment and provide
a firm base and supports in order to prevent vibrations
from exceeding the standard.
The alternator is designed to work with vibration's
values as reported in ISO 8528-9.
Alignment of single bearing generators is critical
because it may give rise to vibrations along the coupling
between engine and generator. For this purpose special
attention must be given to the alternator to engine
as sem bly, providing a solid base and implementing
anti-vibration dampers to support the engine/alternator
assembly.
Dual bearing generators require a rigid frame to
support the engine/generator so that a good base is
established for a precise alignment. This frame should
be anchored to the base with anti-vibration dampers. In
order to minimize twist oscillations, it is advisable to use
a suitably sized flexible joint.
In belt transmissions applied to dual bearing generators
it is essential that the pulley diameters and constructions
permit the load applied to the shaft to be centred with
the length of the nub. The acceptable loads can be
requested directly to the Sincro Technical Office.

6. INSTALLATION

6.1 Lifting

Lift and handle the generator with suitable equipment
either on a pallet or by the lifting lugs located on the
generator in the positions indicated in the figure.
When lifting the HB generator use equipment with a
load bearing capacity of at least 200kg.
When lifting the IB generator use equipment with a
load bearing capacity of at least 300kg.
An insuffi cient loadbearing capacity can
cause severe injury and damage.
CAUTION!
The lifting lugs on the generator have been
designed for lifting only the generator and
not the whole generating set.
CAUTION!
When lifting and handling single bearing generators they
must be kept horizontal in order to avoid, if operations
should go wrong, the rotor from slipping out and being
damaged and possibly causing severe injury.

6.2 Mounting on engine

For tightening torques refer to section 6.2.3.
For mechanical connections it is recommended to use
screws in class 8.8.
Before assembly, check that the coupling
seats (both on generator and engine) are
in order and perfectly clean.
CAUTION!
