ATTENTION

The alternator is supplied with the voltage regulator (AVR) connected to operate at the alternator rated
characteristics;

In case of maintenance or modification of the alternator wiring connections, connect correctly the cables E1,
E3/4 and 3 on the AVR, as follows:
- The cables E1 and E3/4 refers to AVR sensing voltage.
- The cables 3 and E3/4 refers to AVR power supply.

In alternators with 12 terminals, always connect the alternator cables E1 and E3/4 on the AVR terminals E1
and E3/4, regardless of connection type or alternator rated voltage. In these cases, the AVR terminal E2 should
not be used.
