¹ Item not supplied by WEG;
² 5A/250Vac switch to turn ON/OFF the regulator;
³ JR, JS and JT jumpers – Sensing voltage selector (pins 1-2 = 160 to 300Vac, pins 2-3 = 320 to 600Vac);

JCR jumper - Sensing voltage type selector (pins 1-2 = three-phase sensing voltage, pins 2-3 = single-phase sensing voltage).
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.
