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
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
Sudden Movement Hazard. Make sure that the elevator is not occupied when you do elevator test operations
or drive setup. If the elevator test operations or drive setup are incorrect, it can cause serious injury or death if the elevator car
does not stop correctly.
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.
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.
WARNING
Fire Hazard. Tighten screws 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 and cause serious injury or death.
WARNING
Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. A short circuit on the output
can cause serious injury or death.
WARNING
Electrical Shock Hazard. When there is a DC component in the protective earthing conductor, the drive can
cause a residual current. When a residual current operated protective or monitoring device prevents direct or indirect contact,
always use a type B Residual Current Monitor/Residual Current Device (RCM/RCD) as specified by IEC/EN 60755. If you do
not use the correct RCM/RCD, it can cause serious injury or death.
WARNING
Electrical Shock Hazard. Ground the neutral point on the power supply of drive models 4xxxC to comply with
the EMC Directive before you turn on the EMC filter. If you turn ON the EMC filter, but you do not ground the neutral point, it can
cause serious injury or death.
WARNING
Crush Hazard. Test the system to make sure that the drive operates safely after you wire the drive and set
parameters. If you do not test the system, it can cause damage to equipment or serious injury or death.
WARNING
Electrical Shock Hazard. After the drive blows a fuse or trips an RCM/RCD, do not immediately energize the
drive or operate peripheral devices. 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. If you do not know the
cause of the problem, contact Yaskawa before you energize the drive or peripheral devices. If you do not fix the problem before
you operate the drive or peripheral devices, it can cause serious injury or death.
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 31,000 RMS symmetrical amperes, 240 Vac maximum (200 V
Class), 480 Vac maximum (400 V Class). Incorrect branch circuit short circuit protection can cause serious injury or death.
WARNING
Fire Hazard. Remove the insulation from the connection wire ends to the length shown in "Wire Stripping
Length". If you pinch the insulation in the wire terminals, it can cause serious injury or death from fire.
WARNING
Fire Hazard. Make sure that there are no loose stranded wires or frayed wires in the wire core after wiring is
complete. Loose stranded wires or frayed wires in the wire core can create a short circuit and cause serious injury or death from
electrical shock or fire.
CAUTION
Crush Hazard. Tighten terminal cover screws and hold the case safely when you move the drive. If the drive
or covers fall, it can cause moderate injury.
CAUTION
Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum of 15 minutes, then
make sure that the heatsink is cool before you replace the cooling fans. If you touch a hot drive heatsink, it can burn you.
