Caution Install external breakers and take other safety measures against short-circuiting in
external wiring. Not doing so may result in fire.
Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup-
ply voltage. An incorrect power supply may result in fire, injury, or malfunction.
Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.
Not doing so may result in fire.
Caution Be sure to wire correctly and securely. Not doing so may result in injury or damage to
the product.
Caution Be sure to firmly tighten the screws on the terminal block. Not doing so may result in
fire, injury, or damage to the product.
Caution Do not connect an AC power to the U, V, or W output. Doing so may result in damage
to the product or malfunction.
Caution Set the multi-function contact input parameter for NC contact terminals (e.g., 3-wire
sequence) before wiring them. If the parameter’s default setting is used, the motor
may start running when the input terminal S2 is turned ON.
Operation and Adjustment Precautions
WARNING Turn ON the input power supply only after mounting the front cover, terminal covers,
bottom cover, Operator, and optional items. Not doing so may result in electrical
shock.
WARNING Do not remove the front cover, terminal covers, bottom cover, Operator, or optional
items while the power is being supplied. Not doing so may result in electrical shock or
damage to the product.
WARNING Do not operate the Operator or switches with wet hands. Doing so may result in
electrical shock.
WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
WARNING Do not come close to the machine when using the error retry function because the
machine may abruptly start when stopped by an alarm. Doing so may result in injury.
WARNING Do not come close to the machine immediately after resetting momentary power
interruption to avoid an unexpected restart (if operation is set to be continued in the
processing selection function after momentary power interruption is reset). Doing so
may result in injury.
