2.1 Section Safety
WARNING
Crush Hazard
Use a dedicated lifting device when moving or positioning the drive.
Failure to comply may result in serious injury or death from falling equipment.
Use screws to securely affix the drive front cover, terminal blocks, and other drive components prior to vertical
suspension.
Failure to comply may result in serious injury or death from falling equipment.
Do not subject the drive to vibration or impact greater than 1.96 m/s
2 (0.2 G) while it is suspended by the cables.
Failure to comply may result in serious injury or death from falling equipment.
Do not attempt to flip the drive over or leave the drive unattended while it is suspended by the wires.
Failure to comply may result in serious injury or death from falling equipment.
CAUTION
Crush Hazard
Do not carry the drive by the front cover or the terminal cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Equipment Hazard
Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during drive installation
and project construction.
Failure to comply could result in damage to the drive. Place a temporary cover over the top during installation. Be sure to
remove the temporary cover before start-up, as the cover will reduce ventilation and cause the unit to overheat.
Observe proper electrostatic discharge (ESD) procedures when handling the drive.
Failure to comply could result in ESD damage to the drive circuitry.
Operating the motor in the low-speed range diminishes the cooling effects, increases motor temperature, and may
lead to motor damage by overheating.
Reduce the motor torque in the low-speed range whenever using a standard blower cooled motor. If 100% torque is required
continuously at low speed, consider using a special drive or vector-control motor. Select a motor that is compatible with the
required load torque and operating speed range.
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.
Continuously operating an oil-lubricated motor in the low-speed range may result in burning.
