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.
NOTE
To obtain the wiring diagrams of the alternator of frame 400 and higher, refer to WEG.
