4.8.1.3 Electronic voltage regulator connections

The electronic regulator is factory set and electrically
connected to the alternator rated voltage.
ATTENTION
When there is a change in the alternator
main connections for voltage change, it is
also necessary to change the connections of
the reference voltage cables in the voltage
regulator according to the specific wiring
diagram.

4.8.1.4 Terminal identification

Main terminals (connection cables of the stator phases)
1 up to 12, N
Connection terminals on the voltage regulator
E1 or E2 (brown) – Feedback of single-phase voltage.
E3/4 (green) – Common of the circuit of supply and of the
feedback power of the single phase of the voltage
regulator.
R (blue), S(gray) and T(orange) – feedback of three-phase
voltage.
3 (yellow) – Supply of the power circuit of the voltage
regulator.
F+ (red) and F- (black) – Main excitatory field
AX1 (blue), AX2 (gray) and AX3 (orange) – Auxiliary exciter
- supply of power circuit of the voltage regulator – model
GPA.
N (white) – Feedback of single-phase voltage (GPA)
