15.2 CONNETION 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 N should be in the range of
170 to 250 Vac. See below a connection example in a 380Vac phase to phase and 220Vac phase to neutral generator.
For regulator connections in an alternator with a different voltage than what is mentioned in the example, please contact
the regulator manufacturer.

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.
