DANGER
To Prevent Electric Shock
ƕ Never wire the AC drive while the power is on.
ƕ Always keep the MCCB in the off state.
WARNING
T
o Prevent Overheating and Fire
ƕ When installing the drive inside the enclosed cabinet, use the cooling fan or air
conditioner to keep the air inlet temperature below 50°C.
CAUTION
To Prevent Damage to the Equipment
ƕ Cover the top of the drive with a temporary cloth or paper during installation so as to prevent foreign matter such as metal
shavings, oil and water from falling into the drive. After the installation is completed, remove the temporary cloth or paper.
ƕ Follow the proper electrostatic discharge (ESD) procedures when operating the AC
drive. Failure to comply will damage the internal circuit of the drive.
ƕ Operating the motor at low speed lowers the cooling effect and increases the motor temperature, which
will result in damage to the motor. The motor speed range differs with the lubrication mode and the motor
manufacturer. When operating the motor out of the speed range, contact the manufacturer.
ƕ The torque characteristic is different with drive operation compared with operation by commercial
power supply. Please check the load torque characteristic of the connected machine.
ƕ Pay attention to the load torque characteristic when selecting the drive capacity. In addition, when the distance between the
motor and drive is long, use a cable thick enough to connect the motor and the drive to prevent motor torque reduction
