DANGER
To Prevent Electric Shock
ƕ Never wire the AC drive while the power is on. Cut off all power supplies and wait for at least ten minutes
before any checking work so that the residual voltage on capacitors can discharge safely.
ƕ Never modify wiring, disconnect the cable, remove the optional extension card or replace the cooling fan while the drive is running.
ƕ Make sure to connect the grounding terminal of the motor to ground. Failure to comply
may result in electric shock due to touching the motor housing.

ground reliably at one end to prevent the drive malfunction.
ƕ Never modify the drive circuitry. Failure to comply will damage the AC drive.
ƕ Make sure to connect the output terminals of the AC drive and the motor terminals correctly.
If it is necessary to change the motor rotation direction, exchange any of U, V, W cables of the AC drive.
