WEG AVR-A-OPT-03 Installation, Operation And Maintenance Manual page 19

ATTENTION
1. Before connecting the regulator to the generator, verify in the installation manual, the reference nominal
voltage.
2. The sensing voltage can be different than the alternatorphase voltage. Note the point where the sensing
voltage is taken from (middle of the phase or complete phase).
3. If the reference voltage is not equal to the output voltage of the generator, do not make the connections
without consulting the service department.
14.2 CONNECTION WITHOUT AUXILIARY COIL
The connection diagram below can only be used when there is not an auxiliary coil present and where the power for the
regulator power circuit is obtained from the alternatorphases. The voltage between pins 3 and E3/4 should be in the range
of 170 to 250 Vac. See below a connection example in a 220 Vac phase to phase generator. For regulator connections in
a alternatorwith a different voltage than what is mentioned in the example, please contact the regulator manufacturer.
