wiring of power supply and the motor
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 the main circuit conductor, 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 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 the bolts (nuts) for main circuit
wiring, which are provided on the front side of the conductor.
