• 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 phases must be matched.)

• When wiring the inverter main circuit conductor of the FR-F840-05470(250K) or higher, tighten a nut from the right side of the

conductor. When wiring two cables, place cables on both sides of the conductor. For wiring, use bolts (nuts) provided with the

inverter. (Refer to the following figure.)

 Handling of the wiring cover

(For the FR-F820-00630(15K) to 00930(22K) and FR-F840-00310(15K) to 00620(30K))

For the hook of the wiring cover, cut off the necessary parts using a pair of needle-nose pliers etc.

• Cut off the same number of lugs as wires. If parts where no wire is put through have been cut off (10 mm or more), protective

structure (IEC 60529) becomes an open type (IP00).
