a. Machine is factory-preset to 3-phase, 400 V.
b. In start function the shaft rotates clockwise.
c. At the power stage the power circuit to the mains transformer is to be plugg e d
in according to the supply voltage.
d. For 3-phase 230 V supply, switch to motor to
∆∆
(delta), for 3-phase 400 V or 415 V to
star.
e. If direction of rotation is incorrect, exchange 2 phases at main supply.
