The internal capacitor remains charged even after the power supplyis turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock,wait at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level.WARNINGSudden Movement HazardSystem may start unexpectedly upon application of power, resulting in death or serious injury.Clear all personnel from the drive, motor and machine area before applying power. Secure covers, couplings, shaft keys andmachine loads before applying power to the drive.Electrical Shock HazardDo not attempt to modify or alter the drive in any way not explained in this manual.Failure to comply could result in death or serious injury.Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.Do not allow unqualified personnel to use equipment.Failure to comply could result in death or serious injury.Maintenance, inspection, and replacement of parts must be performed only by authorized personnel familiar with installation,adjustment and maintenance of AC drives.Do not remove covers or touch circuit boards while the power is on.Failure to comply could result in death or serious injury.Fire HazardDo not use an improper voltage source.Failure to comply could result in death or serious injury by fire.Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.Crush HazardDo not use this drive in lifting applications without installing external safety circuitry to prevent accidental droppingof the load.The drive does not possess built-in load drop protection for lifting applications.Failure to comply could result in death or serious injury from falling loads.Install electrical and/or mechanical safety circuit mechanisms independent of drive circuitry.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.i.2 General Safety12 YASKAWA ELECTRIC SIEP C710606 31B YASKAWA AC Drive – J1000 Technical Manualhttp://nicontrols.com
