NOTE
• Make sure the power cables are connected to the R/L1, S/L2, and T/L3 of the converter unit. (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 the U, V, and W of the inverter. (The phases must be matched.)
• When wiring cables to the main circuit conductor, tighten each nut from the right of the conductor as seen from the front of the
unit.
When wiring two cables, place cables on both sides of the conductor. (Refer to the diagram below.)
For wiring, use bolts (nuts) provided with the inverter.
• When wiring the main circuit conductor (R/L1, S/L2, T/L3) of the converter unit (FR-CC2), use bolts (nuts) for wiring the main
circuit before the conductor.
