WARNING
Electrical Shock Hazard. Do not operate equipment when covers are missing. Some figures in this section
include drives without covers or safety shields to more clearly show the inside of the drive. Replace covers and shields before
operation. Use drives only as specified by the instructions. Failure to obey can cause death or serious injury.Electrical Shock
Hazard. Always ground the motor-side grounding terminal. Contacting the motor case can cause death or serious injury from
incorrect equipment grounding.Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices
after the drive blows a fuse or trips an ELCB. 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.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.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.Electrical Shock Hazard. Do not remove covers or touch circuit boards
while the drive is energized. Failure to obey can cause death or serious injury.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.Fire Hazard. Tighten screws against the bit at an angle in
the specified range shown in this manual. If you tighten the screws at an angle not in the specified range, you can have loose
connections that can cause damage to the terminal block or start a fire.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.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.Sudden Movement Hazard. Do not do work on
the drive without eye protection. Wear eye protection before you start work on the drive. Failure to obey could cause serious
injury or death.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.
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.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.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.Do not change the drive circuitry. Failure to obey can cause
damage to the drive and will void warranty. Yaskawa is not responsible for modifications of the product made by the user.Make
sure that all connections are correct after you install the drive and connecting peripheral devices. Failure to obey can cause
damage to the drive.
