• Wires and Terminal Lugs
Refer to the following table for wires, terminal lugs, and screws used to connect the inverter power input (R, S, T) and
output (U, V, W). Input and motor output terminal blocks are intended only for use with ring type connectors.

• Power and Motor Connection
R S T G N B1 B2 U V W
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.

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