Note:
Be aware that serious injury or death may result if the warnings described in this manual are not observed. Yaskawa assumes no
responsibility for injuries or equipment damage to your company or customers that are caused by a failure to observe the information
contained in this manual.
•
Read this manual carefully when mounting, operating, and repairing AC drives and Communication options.
•
Follow all warnings, cautions, and instructions.
•
All work should be carried out by qualified personnel.
•
Ensure the drive is installed to an area that matches the following conditions.
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. Failure to obey will cause death or serious injury.
WARNING
Fire Hazard. Do not connect power supply wiring to drive output terminals U/T1, V/T2, and W/T3. Connect
power supply wiring to main circuit input terminals R/L1, S/L2, and T/L3. Failure to obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Do not make changes to the drive body or drive circuitry. Failure to obey can cause
death or serious injury and will void warranty. Yaskawa is not responsible for changes to the product made by the user.
WARNING
Electrical Shock Hazard. Only let authorized persons install, wire, maintain, examine, replace parts, and
repair the drive. Failure to obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Always ground the motor-side grounding terminal. Contacting the motor case can
cause death or serious injury from incorrect equipment grounding.
WARNING
Electrical Shock Hazard. Do not work on the drive or around the drive while wearing loose clothing or jewelry.
Tighten loose clothing and remove all metal objects such as watches or rings. Failure to obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. The leakage current of the drive will be more than 3.5 mA in drive models 2xxxB,
2xxxC, 4002B to 4371B, 4002C to 4371C (with built-in EMC filter turned ON) and 4389 to 4675. The IEC/EN 61800-5-1: 2007
standard specifies that users must wire the power supply to automatically turn off when the protective ground wire disconnects.
Users can also connect a protective ground wire that has a minimum cross-sectional area of 10 mm
2
(copper wire) or 16 mm
2
(aluminum wire). Failure to obey these standards can cause death or serious injury.
WARNING
Sudden Movement Hazard. Remove all persons and objects from the area around the drive, motor, and load
before starting Auto-Tuning. The drive and motor can start suddenly during Auto-Tuning and cause death or serious injury.
WARNING
Sudden Movement Hazard. Remove all persons and objects from the area around the drive, motor, and
machine area and attach covers, couplings, shaft keys, and machine loads before energizing the drive. Failure to obey can
cause death or serious injury.
WARNING
Fire Hazard. Do not use the main circuit power supply (Overcurrent Category III) at incorrect voltages. Make
sure that the drive rated voltage aligns with the power supply voltage before energizing the drive. Failure to obey can cause
death or serious injury.
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. Failure to obey can cause
death or serious injury.
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.
WARNING
Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. Failure to obey can cause
death or serious injury.
WARNING
Electrical Shock Hazard. Always use a type B Residual Current Monitor/Residual Current Device (RCM/RCD)
where a residual current operated protective or monitoring device protects against direct or indirect contact as specified by IEC/
EN 60755 The drive can cause a residual current with a DC component in the protective earthing conductor. Failure to obey can
cause death or serious injury.
WARNING
Electrical Shock Hazard. Ground the neutral point on the power supply of drive models 2xxxB/C and 4xxxA/B/
C to comply with the EMC Directive before turning on the EMC filter or if there is high resistance grounding. If the EMC filter is
switched ON without the neutral point being grounded or if there is high resistance grounding, it can cause death or serious
injury.
