Wiring
CAUTION:
E
● Before wiring cables to the main circuit terminals, remove the wiring cover. For the FR-E740-
170SC-ENE or lower or FRE720S-110SC-ENE or lower inverter, additionally remove the
Ethernet board.
To remove the Ethernet board, refer to section 3.7.4. To remove the wiring cover, refer to
section 2.3.
● 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 counter
clockwise direction when viewed from the motor shaft.
