When an option other than the DC reactor must be connected to terminal P/+, use terminal P/+ (for option connection).
NOTE
• Make sure the power cables are connected to the R/L1, S/L2, and T/L3. (Phase need not be matched.) Never connect the
power cable to the U, V, and W of the inverter. Doing so will damage the inverter.
• Connect the motor to U, V, and W. The phase need to be matched.
• When wiring the inverter main circuit conductor of the FR-A860-04420, 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.
