The following diagram shows the positions of R1/L11, S1/L21, and the charge lamp.

The terminals P3 and PR of the FR-F820-01540(37K) are not equipped with screws. Do not connect anything to these.

For the FR-F840-01800(75K), a jumper is not installed across the terminals P1 and P/+. Always connect a DC reactor (FR-HEL), which is available as an option, across
the terminals P1 and P/+.
NOTE
• Make sure the power cables are connected to the R/L1, S/L2, T/L3. (Phase need not be matched.) Never connect the power cable to the U, V, W of the inverter. Doing
so will damage the inverter.
• Connect the motor to U, V, and W. Turning ON the forward rotation switch (signal) at this time rotates the motor counterclockwise when viewed from the load shaft.
(The phase sequence must be matched.)
• The charge lamp will turn ON when the power is supplied to the main circuit.
• 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 on the right.) For wiring, use
bolts (nuts) provided with the inverter.
