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 damaged 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 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). For wiring, use bolts (nuts)
provided with the inverter.
