15.5 CONNECTION DIAGRAM FOR PARALELL OPERATION (CROSS-CURRENT MODE)
WITH THREE-PHASE SENSING VOLTAGE
1
5A/250Vac switch to turn ON/OFF the regulator;
ATTENTION
1. Before connecting the regulator to the generator, verify in the installation manual, the rated sensing
voltage;
2. The sensing voltage can be different than the generator phase voltage. Note the point where the
sensing voltage is taken from (middle of the phase or complete phase).
3. If the sensing voltage is not equal to the output voltage of the generator, do not make the
connections without consulting the service department.
