Apply 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.

Use copper wires only with 600V, 75
℃
ratings .
Motor
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 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.
