3.1 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 show drives without covers or safety shields to show details. Be sure to reinstall covers orshields before operating the drives and run the drives according to the instructions described in this manual.Make sure the protective earthing conductor complies with technical standards and local safety regulations.Failure to comply may result in death or serious injury.Always use appropriate equipment for Ground Fault Circuit Interrupters (GFCIs).The drive can cause a residual current with a DC component in the protective earthing conductor. Where a residual currentoperated protective or monitoring device is used for protection in case of direct or indirect contact, always use a type B GFCIaccording to IEC/EN 60755.Always ground the motor-side grounding terminal.Improper equipment grounding could result in death or serious injury by contacting the motor case.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.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 withinstallation, adjustment, and maintenance of AC drives.Do not touch any terminals before the capacitors have fully discharged.Failure to comply could result in death or serious injury.Before wiring terminals, disconnect all power to the equipment. The internal capacitor remains charged even after the powersupply is turned off. After shutting off the power, wait for at least the amount of time specified on the drive before touchingany components.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 improper combustible materials.Failure to comply could result in death or serious injury by fire.Do not install the drive to a combustible surface. Never place combustible materials on the drive.3.1 Section Safety68 YASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual
