6. VOLTAGE AND OUTPUT FREQUENCY ON THE THREE PHASE ALTERNATORS
These alternators are designed to supply the voltage at:
⇒ 400 V at 50 Hz or 480 V at 60 Hz with star/neutral connection
II
⇒ 230 V at 50 Hz or 276 V at 60 Hz with delta connection

7. SINgLE PHASE DUTY OF THREE-PHASE ALTERNATORS
1,550
1,550
The output power in single-phase in continuous duty is approximately 65% of three-phase output
1,350
power in case of line-to-line voltage and 60% (E1S10/E1S11), 40% (E1S13) in case of phase voltage (star
1,350
connection).

8. VOLTAgE CALIBRATION AND REVOLVINg SPEED
0,648
The calibration of voltage should be carried out by qualified personnel only because of electrocution
0,540
hazard.
0,540
A checkout of the alternator's output voltage should be carried out at the nominal revolving speed (3000 r.p.m. for the
0,540
alternators at 2 poles and 1500 r.p.m. for those at 4 poles).
0,540
The alternators are calibrated to distribute the nominal voltage.
0,540
Light deviations of the output voltage can be caused by a revolving speed which is different from the nominal one.
The output voltage changes proportionally to the revolving speed.
To correct the no-load voltage of the alternator at a specific revolving speed, it is necessary to act on the air gap of the
compound transformer as under described (see Figure 10).

(A)
1) Loose the tightening of two screw nuts N.
EXC
4,00
2) Modify the height of air gap considering that:
4,10
a) increasing it the voltage grows;
4,20
b) decreasing it the voltage lows down;
4,50
slight voltage variations they can be obtained with a small hammer and a screwdriver. In case the variation of
4,30
demanded voltage exceeds 5% is necessary to proceed to the replacement of the insulating thickness (T) that forms
4,80
the air gap.
4,45
3) Once regulation is effected, tighten the two screw nuts N.
7,75
ATTENTION:
7,50
for a correct operation of the alternator the voltage can not exceed +/- 5% of the plate value.

9. gENERAL NOTE
7,70
Operation in particular settings
7,50
If the alternator is going to be used within a soundproof generating set, make sure that only fresh air enters it.
7,70
This can be ensured by placing the alternator's air inlet near the external air intake.
Moreover, remember that the quantity of air required is:
