3.2 Main circuit terminal specifications

3.2.1 Terminal arrangement of the main circuit terminal, power supply and the motor wiring

FR-A741-5.5K, 7.5K

FR-A741-11K, 15K

FR-A741-18.5K to 45K

FR-A741-55K

ACHTUNG

The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to 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, W. At this time turning on the forward rotation switch (signal) rotates the motor in the clockwise direction

when viewed on the motor shaft.
