Power and Motor Connection

3 Phase

Power Input

Power supply must be connected to the R, S, and T terminals.

Connecting it to the U, V, and W terminals causes internal damages to the inverter. Arranging the phase sequence is not necessary.

Motor

Motor should be connected to the U, V, and W terminals.

If the forward command (FX) is on, the motor should rotate counter clockwise when viewed from the load side of the motor. If the motor rotates in the reverse, switch the U and V terminals.

8Apply the rated torque to terminal screws. Loose screws can cause of short circuit or malfunction. Tightening the screws too much can damage the terminals and cause a short circuit or malfunction.

9Use copper wires only with 600V, 75ratings.
