5.1 Section SafetyDANGERElectrical Shock HazardBefore servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the powersupply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electricshock, wait for at least the time specified on the warning label, once all indicators are OFF, measure for unsafe voltages toconfirm the drive is safe prior to servicing.Failure to comply will result in death or serious injury.WARNINGElectrical Shock HazardDo not operate equipment with covers removed.Failure to comply could result in death or serious injury.The diagrams in this section may illustrate drives without covers or safety shields to display details. Be sure to reinstall coversor shields before operating the drives and run the drives according to the instructions described in this manual.Always ground the motor-side grounding terminal.Improper equipment grounding could result in death or serious injury by contacting the motor case.Do not touch terminals before the capacitors have fully discharged.Failure to comply could result in death or serious injury.Before servicing, disconnect all power to the equipment. 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 for at least the time specified on the warning label; after all indicators are OFF, measure for unsafe voltages to confirmthe drive is safe prior to servicing.After blowing a fuse or tripping a GFCI, do not attempt to restart the drive or operate peripheral devices until fiveminutes pass and CHARGE lamp is OFF.Failure to comply could result in death, serious injury, and damage to the drive.Check wiring and peripheral device ratings to identify the cause of trips.Contact your supplier if the cause cannot be identified.Do not allow unqualified personnel to perform work on the drive.Failure to comply could result in death or serious injury.Installation, maintenance, inspection and servicing must be performed only by authorized personnel familiar with installation,adjustment and maintenance of AC drives.Do not perform work on the drive while wearing loose clothing, jewelry, or without eye protection.Failure to comply could result in death or serious injury.Remove all metal objects such as watches and rings, secure loose clothing and wear eye protection before beginning workon the drive.Do not remove covers or touch circuit boards while the power is on.Failure to comply could result in death or serious injury.Fire HazardTighten all terminal screws to the specified tightening torque.Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.Do 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 drive input power before applying power.5.1 Section Safety192 YASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual
