2.1 Section SafetyWARNINGFire HazardProvide sufficient cooling with a fan or air conditioning unit when installing the drive inside an enclosed panel orcabinet.Failure to comply could result in overheating and fire.The airflow over an IP20/Open-Chassis drive should be less than 50 °C, while an IP20/NEMA Type 1 drive using the NEMAType 1 Kit option should have an airflow cooler than 40 °C.CAUTIONCrush HazardDo 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.NOTICEObserve 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 maylead 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 requiredcontinuously at low speed, consider using a special drive or vector motor. Select a motor that is compatible with the requiredload 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.2.1 Section Safety24 YASKAWA ELECTRIC SIEP C710606 31B YASKAWA AC Drive – J1000 Technical Manualhttp://nicontrols.com
