Do not put flammable or combustible materials on top of the drive and do not install the drive
near flammable or combustible materials. Attach the drive to metal or other noncombustible
material.
Failure to obey can cause death or serious injury.
Do not use the main circuit power supply (Overcurrent Category III) at incorrect voltages. Make
sure that the drive rated voltage aligns with the power supply voltage before energizing the
drive.
Failure to obey can cause death or serious injury.
When installing dynamic braking options, wire the components as specified by the wiring
diagrams.
Failure to obey can result in fire, death or serious injury. Incorrect wiring can cause damage to braking
components.
When installing the drive into a closed cabin or cabinet, use a cooling fan or cooler to decrease
the temperature around the drive. Make sure that the intake air temperature to the drive is 50 °C
(122 °F) or less for open chassis type drives, (IP20) and 40 °C (104 °F) or less for enclosed wall-
mounted type (UL Type1) drives.
Failure to obey can cause the drive to overheat and cause fire, death or serious injury.
Only approved personnel can operate a crane or hoist to move the drive.
Failure to obey can cause death or serious injury from falling equipment.
Use screws to correctly attach the drive front cover, terminal blocks, and other drive
components before hanging the drive vertically.
Failure to obey can cause serious injury or death from falling equipment.
Prevent more than 1.96 m/s
Failure to obey can cause death or serious injury from falling equipment.
Do not try to flip over a hanging drive or leave a hanging drive unattended.
Failure to obey can cause death or serious injury from falling equipment.
Use a lifting mechanism made to move large drives when necessary.
Failure to obey can cause death or serious injury from falling equipment.
Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before
moving the drive.
Failure to obey can cause minor to moderate injury.
Do not let unwanted objects, for example metal shavings or wire clippings, fall into the drive
during drive installation and project construction. Put a temporary cover over the top of the
drive during installation. Remove the temporary cover before start-up or the drive will overheat.
Failure to obey can cause damage to the drive.
Observe correct electrostatic discharge (ESD) procedures when touching the drive.
Failure to obey can cause ESD damage to the drive circuitry.
To use a standard blower-cooled motor, reduce the motor torque in the low-speed range. If 100%
torque is continuously necessary at low speed, use a special motor or vector control motor.
Select a motor that is compatible with the necessary load torque and operating speed range.
Operating the motor in the low speed range decreases the cooling effects, increases motor temperature, and can
cause overheating and motor damage.
