The terminals P3 and PR of the FR-F820-01540(37K) are not equipped with screws. Do not connect anything to these.
*3
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/+.

For terminal layout and wiring of the converter unit (FR-CC2) refer to the FR-CC2 Instruction Manual.
CAUTION
The power supply cables must be connected to R/L1, S/L2, T/L3. Never connect the power cable to the U, V, W, of the
inverter. Doing so will damage the inverter. (Phase sequence needs not to be matched.)
Connect the motor to U, V, W. At this time turning on the forward rotation switch (signal) rotates the motor in the
clockwise direction when viewed from the motor 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). For wiring,
use bolts (nuts) provided with the inverter.
For wiring the main circuit conductor of the converter unit (FR-CC2) refer to the FR-CC2 Instruction Manual.
