*

Make sure that the input voltage is:
Three phase 200 to 220 V/50 Hz, 200 to 230 V/60 Hz

     Three phase 380 to 415 V/50 Hz, 400 to 460 V/60 Hz

*

Be sure not to input a single phase to a 3 phase type.
Otherwise, there is a danger of fire.

*

Be sure not to connect AC power supply to the output terminals
[U (T1), V (T2), W (T3)].
Otherwise, there is a danger of injury and/or fire.

Fasten the screws with the specified fastening torque.  Check so that
there is no loosening of screws.
Otherwise, there is a danger of fire.

*

Be sure to install an earth leakage breaker.

    The ground fault protection is designed to detect current flowing to the

ground upon power on. This function is to protect the inverter, not
people. Install the earth leakage breaker to protect against the ground
fault on wires between the inverter and the motor. (Use a breaker that is
very sensitive to high frequency current so as not to cause malfunction.)

*

Be sure to set the fuse(s) (the same phase as the main power supply)
in the operation circuit.
Otherwise, there is a danger of fire.

*

As for motor leads, earth leakage breakers and electromagnetic
contactors, be sure to use the equivalent ones with the specified
capacity (rated).
Otherwise, there is a danger of fire.

*

Connection to wiring terminal must be reliabily fixed with two means
of support.
