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:
Failure to obey the safety messages in the manual can cause serious injury or death. Yaskawa is not responsible for
injuries or damage to equipment caused by ignoring the safety messages.
• 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, measure 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. The drive has internal capacitors that stay charged after you
de-energize the drive.
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
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
Electrical Shock Hazard. Make sure that the protective ground wire conforms to technical
standards and local safety regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the
power supply to automatically de-energize when the protective ground wire disconnects. If you turn on the
internal EMC filter, the leakage current of the drive will be more than 3.5 mA. You can also connect a protective
ground wire that has a minimum cross-sectional area of 10 mm
and regulations, it can 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
Fire Hazard. Do not use the main circuit power supply (Overvoltage Category III) at
incorrect voltages. Operate the drive in the specification range of the input voltage on the drive nameplate.
Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.
WARNING
Fire Hazard. Do not put flammable or combustible materials on top of the drive and do not
install the drive near flammable or combustible materials. Attach the drive to metal or other noncombustible
material. Flammable and combustible materials can start a fire and cause serious injury or death.
WARNING
Fire Hazard. Tighten all terminal screws to the correct tightening torque. Connections that
are too loose or too tight can cause incorrect operation and damage to the drive. Incorrect connections can also
cause death or serious injury from fire.
