Wiring
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 counterclockwise direction when viewed from the motor shaft.
· When wiring the inverter main circuit conductor of the 220K or more, 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.
• Handling of the wiring cover
(FR-A720-15K, 18.5K, 22K, FR-A740-18.5K, 22K)
For the hook of the wiring cover, cut off the necessary
parts using a pair of long-nose pliers etc.
CAUTION
Cut off the same number of lugs as wires. If parts where
no wire is put through has been cut off (10mm or more),
protective structure (JEM1030) becomes an open type
(IP00).
