INSTALLATION AND WIRING
• 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.
2.5.3 Wiring method
(1) Remove the front cover of the inverter. (Refer to page 18)
(2) For the FR-F846-00470(22K) or lower, remove the wiring cover installation screws (hexalobular screws, screw size: M5,
screwdriver size: T25, tightening torque: 2.8 to 3.6 N·m) to remove the wiring cover.
(3) For the FR-F846-00470(22K) or lower, remove the protective bushes from the wiring cover.
For the FR-F846-00620(30K) to FR-F846-01160(55K), remove the protective bushes from the bottom of the inverter.
For the FR-F846-01800(75K) or higher, remove the protective bushes from the bottom and the side of the inverter.
(Do not remove the protective bushes from the holes that are not used for wiring of cables.)
• For the FR-F846-01800(75K) or higher, do not remove the screws on the bottom of the inverter. The IPX5 waterproof
performance may be impaired.
