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.
