¹ Item not supplied by GRAMEYER, please verify ratio specification (PAR/1 or PAR/5);
² if there is no Potentiometer connected, keep terminals short circuited;
³ 10A/250Vac switch to turn ON /OFF the regulator (Item not supplied by GRAMEYER)
* Output line voltage from generator in accordance to sensing class and the voltage level of the regulator power supply (Table
4.1).
ATTENTION
1. Before connecting the regulator to the generator, verify in the installation manual, the reference nominal
voltage.
2. When using an auxiliary coil, the connector E3/4, reference of the regulator circuit, should be the mandatory
