Main circuit terminals
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
Connect the motor to U, V, and W. The phase need to 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 wires, place wires on both sides of the
conductor. (Refer to the drawing.) For wiring, use bolts (nuts) provided with the inverter.

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 (JEM1030) becomes an open type (IP00).
