General Safety Instructions
Yaskawa Electric manufactures and supplies electronic components for a variety of industrial applications. The
selection and application of Yaskawa products is the responsibility of the designer of the equipment or the customer
who assembles the final product. Yaskawa is not responsible for how our products are incorporated into the final
system design. In all cases, Yaskawa products should not be incorporated into a product or design as the exclusive or
sole safety control function. All control functions are designed to dynamically detect failures and operate safely
without exception. All products that are designed to incorporate parts manufactured by Yaskawa must be provided to
the end user and include proper warnings and instructions regarding their safe use and operation. All warnings from
Yaskawa must be promptly issued to the end user. Yaskawa offers warranties only for the quality of our products, in
compliance with standards and specifications that are described in the manual. Yaskawa does not offer other
warranties, either explicit or implied. Injuries, property damage, and lost business opportunities caused by improper
storage or handling and negligence oversight on the part of your company or your customers will void Yaskawa's
warranty for the product.
Note:
• Read this manual carefully when mounting, operating, and repairing AC drives.
• Obey all warnings, cautions, and notices.
• Approved personnel must perform all work.
• Install the drive according to this manual and local codes.
DANGER! Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor
stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below 50
Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the drive is safe. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
WARNING! Fire Hazard. Do not connect main power supply wiring to drive motor terminals U/T1, V/T2, and W/T3. Connect main
power supply wiring to main circuit input terminals R/L1, S/L2, and T/L3. Incorrect wiring can cause serious injury or death from fire.
WARNING! Electrical Shock Hazard. Do not modify the drive body or drive circuitry. Modifications to drive body and circuitry can
cause serious injury or death, will cause damage to the drive, and will void the warranty. Yaskawa is not responsible for
modifications of the product made by the user.
WARNING! Crush Hazard. Only approved personnel can operate a crane or hoist to move the drive. If unapproved personnel
operate a crane or hoist, it can cause serious injury or death from falling equipment.
WARNING! Electrical Shock Hazard. Only let approved personnel install, wire, maintain, examine, replace parts, and repair the
drive. If personnel are not approved, it can cause serious injury or death.
WARNING! Electrical Shock Hazard. Always ground the motor-side grounding terminal. If you do not ground the equipment
correctly, it can cause serious injury or death if you touch the motor case.
WARNING! Electrical Shock Hazard. Do not wear loose clothing or jewelry when you do work on the drive. Tighten loose clothing
and remove all metal objects, for example watches or rings. Loose clothing can catch on the drive and jewelry can conduct
electricity and cause serious injury or death.
WARNING! Sudden Movement Hazard. Before you do Auto-Tuning, remove all personnel and objects from the area around the
drive, motor, and load. The drive and motor can start suddenly during Auto-Tuning and cause serious injury or death.
WARNING! Sudden Movement Hazard. Remove all personnel and objects from the area around the drive, motor, and machine and
attach covers, couplings, shaft keys, and machine loads before you energize the drive. If personnel are too close or if there are
missing parts, it can cause serious injury or death.
WARNING! Damage to Equipment. Do not apply incorrect voltage to the main circuit of the drive. Operate the drive in the specified
range of the input voltage on the drive nameplate. Voltages that are higher than the permitted nameplate tolerance can cause
damage to the drive.
