The following diagram shows the positions of R1/L11, S1/L21, and the charge lamp.

Terminals P3 and PR of the FR-A820-01540(30K) are not equipped with screws. Do not connect anything to these.

When an option other than the DC reactor must be connected to terminal P/+, use terminal P/+ (for option connection).
NOTE
• 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. 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-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 following figure) For wiring, use bolts (nuts) provided with the inverter.
