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 or
E2, E3/4 and 3 on AVR, as follows:
- The cables E1 or E2 and E3/4 refers to AVR sensing voltage.
- The cables 3 and E3/4, refers to AVR power supply.

In WEG alternators with single voltage (6 or 3 terminals) from 160 to 300V, always connect the alternator
cables E1 and E3/4 on the AVR terminals E1 and E3/4, as the diagrams above;

In WEG alternators with single voltage (6 or 3 terminals) from 320 to 600V, always connect the alternator
cables E2 and E3/4 on the AVR terminals E2 and E3/4, as the diagrams above.
