2.1 Section Safety
WARNING
Fire Hazard
Provide sufficient cooling when installing the drive inside an enclosed panel or cabinet.
Failure to comply could result in overheating and fire.
When multiple drives are placed inside the same enclosure panel, install proper cooling to ensure air entering the enclosure
does not exceed 40 °C.
CAUTION
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Observe proper electrostatic discharge (ESD) procedures when handling the drive.
Failure to comply could result in ESD damage to the drive circuitry.
It may be difficult to perform maintenance on the cooling fans of drives installed in a vertical row inside an
enclosure.
Ensure adequate spacing at the top of the drive to perform cooling fan replacement when required.
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 motor. Select a motor that is compatible with
the required load torque and operating speed range.
Do not operate motors above the maximum rated RPM.
Failure to comply may lead to bearing or other mechanical motor failures.
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.
