Handling of the wiring cover
(FR-A820-00630(11K) to 01250(22K), FR-A840-00310(11K) to 00620(22K))
For the hook of the wiring cover, cut off the necessary parts using a pair of needle-nose pliers etc.
NOTES 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-A840-05470(220K) 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.

(10 mm or more), protective structure (JEM1030) becomes an open type (IP00).
