18. DESCRIPTION OF THE TERMINALS AND JUMPERS CONNECTIONS
FOR WRGA-02 MODEL
R, S, T: Three-phase sensing voltage.
N: Neutral connection. The same terminal as E3/4/N. ¹
E3/4: Common of power circuit supply and single- phase sensing voltage. ¹
S1: Connection to S1 pole of CT for parallelism.
S2: Connection to S2 pole of CT for parallelism.
3: Power Supply.
: Connection to 5KW/3W (for external voltage control).
F+: Connection to positive terminal in the exciter.
F-: Connection to negative terminal in the exciter.
JHz: 50/60Hz jumper (Pins 1-2 = 50 Hz, pins 2-3 = 60 Hz).
JCR: Selector jumper for sensing voltage type (Pins 1-2 = three-phase sensing voltage, pins 2-3 = single-phase sensing
voltage).
JR, JS and JT: Selector Jumper for sensing voltage range: Pins 1-2 = 160 to 300Vac and pins 2-3 = 160 to 300Vac.
A+: Analog voltage input +9Vcc.
A-: Analog voltage input -9Vcc.
UP: Increase voltage through digital input.
CM: Digital input reference.
DOWN: Decrease voltage through digital input.
¹ In case the auxiliary coil is supplied with two cables, it will be necessary to do the sensing voltage connection with the three
phase terminals plus the neutral in the terminals R, S, T and N and the connection of the two auxiliary coil cables in the
terminals 3 and E3/4/N.
