SINGlE PHASE AlTERNATOR
Fasten the flange F to the motor using screws and
washers adequate to the purpose. (fig. 1A).
Apply the rod T for the axial clamping of the rotor, and
screw it tight on the engine shaft. (fig. 1A).
CAUTION
Before assembling verify that the conical coupling parts
are in order and clean.
CAUTION
Caution: before applying the nut, make sure that the
threaded part of the rod enters the rotor, in order to
obtain a tight lock.

Connect the alternator to the electric control panel P4
by joining the C and C1 connectors (Fig 1C); fasten
the connector unit to the shield by fitting it into the C2
housing provided.
Fasten the cover (P4) to the alternator using the 5 V4
screws (self- tapping M5 x 16 screws).
Close the hole on the electric control panel P4 using
the plastic plug; close the holes on the P5 shield (if not
used) using P1 the membrane- type cable glands.
Optional IP23: assemble the two P2 protections by
snapping them into the front shield and then fastening
each one in place using the appropriate V2 self- tapping
M5x16 screw.
Fasten the alternator to the frame using appropriate
vibration- damping supports.

Fasten the complete alternator to the flange using the
4 screws V1 and washers R1 provided (driving torque
25Nm). (fig. 1B).
Lock axially the rotor by placing the washer R2 and
tight the self- locking nut D2 on the rod , using a torque
spanner (driving torque 25 - 30Nm).
PRElIMINARYCHECKS
On receipt it is recommended to inspect the alternator
to find out whether it has got damages during
transportation.
STORAGE
If the alternator is not installed immediately, it should be
kept indoor, in a clean and dry place. Before starting up
the alternator after long periods of inactivity or storage,
the windings insulation resistance must to be measured.
That should be higher than 2 m at room temperature.
If this value cannot be obtained it is necessary to reset
the insulation, drying the windings (using an oven at 60º-
80º C).
MECHANICAl COUPlING
See assembling instructions. Brush generators: always
check to make sure that the brushes are suitably
centered on the slip rings
ElECTRIC CONNECTION
Make sure that the various equipment to be connected
to the generator conforms to the rating plate data. Carry
out the connections as shown in the diagram on page 14
and ground the generator by the terminals supplied for
this purpose. Before using the generator, it is necessary
to make sure that the above mentioned procedures
have been carried out correctly and that no obstacles
to rotor rotation are present. Also check that when the
generator runs in no load condition the current measured
on each outlet on the electric board corresponds to the
recommended rated voltage. It is dangerous to operate
the generator with a load at a RPM different than the
nominal value (max deviation: -2%,+ 5%): this type of
working conditions represents an overload condition.
INSTAllATION
Set up the unit in a well- cooled place. Make sure that
cooling air intake and discharge openings are free and
unblocked. The alternator must suck in clean air only:
the suction of the hot air expelled from the alternator
itself and/ or the prime motor must be avoided, as well
as the suction of motor exhaust fumes, dust and dirt.
MAINTENANCE
The alternator as well as the possible accessories should
always be kept clean. It is recommended to periodically
check that the unit operates without anomalous vibrations
or noises, and the ventilation circuit is not obstructed.
Brush generators: periodically check the wear and the
position of the brushes.
