Installation; Lifting; Mounting On Engine - Sincro SK160 Série Manuel D'utilisation Et De Maintenance

A drop in cooling air flow or inadequate
protection of the generator can lead
to damage and/or malfunction of the
windings.
WARNING!
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 essential that the plant engineer takes all
necessary measures to ensure alignment 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
assembly, providing a solid base and implementing
anti-vibration dampers to support the engine/alternator
assembly.
The terminal box contains the insulated terminals for
connecting the phases and neutral and for the earth
connection.
The neutral is NOT connected to the housing.
The generator is supplied without
a connection to earth; to make this
connection refer to relevant local
regulations. An inefficient earth connection

or safety cut-out can cause injury or death.
The generator fault currents are available on request
to help the plant engineer in sizing the plant and its
components.
An error in installation, use, maintenance
or replacement of parts can cause severe
injury or death, not to mention damage to
the machinery. All work on electrical and/

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 SK160 generator use equipment
with a load bearing capacity of at least 200kg.
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.
An insufficient 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!

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!
