FR-F740-03250 to 04810-NA FR-F740-05470 to 12120-NA
CAUTION
· The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to be matched.) Never connect
the power cable to the U, V, W of the inverter. Doing so will damage the inverter.
· 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-F740-05470 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 below.) For wiring, use
bolts (nuts) provided with the inverter.
