CAUTION
· The power supply cables must be connected to R/L1, S/L2, T/L3. Never connect the power cable
to the U, V, W of the inverter. Doing so will damage the inverter. (Phase sequence needs not to be
matched.)
· Connect the motor to U, V, W. At this time, turning on the forward rotation switch (signal) rotates
the motor in the counterclockwise direction when viewed from the motor shaft.
· When wiring the inverter main circuit conductor of the FR-A740-04320 or more, tighten a nut from
the right side of the conductor. When wiring two wires, place wires on both sides of the conductor.
(Refer to the drawing on the right.) For wiring, use bolts (nuts) provided with the inverter.
