EN 3
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 drive models 4389A to 4675A, 2xxxB/C and 4xxxB/C is more
than 3.5 mA. 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
Crush Hazard. Use a lifting mechanism made to move large drives when necessary. Failure to obey can
cause death or serious injury from falling equipment.
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. Use a type B Residual Current Monitor/Residual Current Device (RCM/RCD) for
protection against contact when using a residual current operated protective device or monitoring device 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. Failure to obey can
cause death or serious injury.
WARNING
Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices after the drive
blows a fuse or trips an RCM/RCD. Wait for the time specified on the warning label at a minimum and make sure that all
indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. Contact Yaskawa
before energizing the drive or peripheral devices if the cause is not known. Failure to obey can cause death or serious injury
and damage to the drive.
WARNING
Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suited for circuits that supply not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V
Class), 480 Vac maximum (400 V Class). Failure to obey can cause death or serious injury.
CAUTION
Crush Hazard. Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before
moving the drive. Failure to obey can cause minor to moderate injury.
CAUTION
Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait 15 minutes minimum, and make
sure that the heatsink is cool to replace the cooling fans. Failure to obey can cause minor to moderate injury.
NOTICE
Observe correct electrostatic discharge (ESD) procedures when touching the drive and circuit boards. Failure
to obey can cause ESD damage to the drive circuitry.
NOTICE
Do not connect or disconnect the motor from the drive while the drive is supplying voltage. Incorrect
equipment sequencing can cause damage to the drive.
NOTICE
Do not do a withstand voltage test or Megger test on the drive. Failure to obey can cause damage to the drive.
NOTICE
Do not connect or operate damaged equipment or equipment with missing parts. Failure to obey can cause
damage to the drive and connected equipment.
NOTICE
Install fuses and an RCM/RCD. Failure to obey can cause damage to the drive.
NOTICE
Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the
ground terminal of the drive. Failure to obey can cause electrical interference and unsatisfactory system performance.
