CONNECTION TO THE GENERATOR OPERATING IN (330 to 600Vca)

Attention

➢

Before connecting the regulator to the generator, refer to the installation manual for the

nominal reference voltage;

➢

The supply voltage

can’t exceed

the maximum voltage specified by the product

;

➢

If the reference voltage is note qual to the output voltage of the generator, do not make the

connections without consulting the service center.
