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
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
Crush Hazard. Use a crane or hoist to move large drives when necessary. If you try to move a large drive without
a crane or hoist, it can 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 Ground Fault Circuit Interrupter (GFCI) as specified by IEC/EN 60755. If you do not use the correct GFCI, 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 a GFCI, 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
Crush Hazard. Only approved personnel can operate a crane or hoist to move the drive. If unapproved personnel
operate a crane or hoist, it can cause serious injury or death from falling equipment.
WARNING
Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suitable for circuits that supply not more than 100,000 RMS symmetrical amperes, 480 Vac maximum (400 V
Class). Incorrect branch circuit short circuit protection can cause serious injury or death.
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.
NOTICE Damage to Equipment. When you touch the drive and circuit boards, make sure that you observe correct
electrostatic discharge (ESD) procedures. If you do not follow procedures, it can cause ESD damage to the drive circuitry.
NOTICE Do not break the electrical connection between the drive and the motor when the drive is outputting voltage.
Incorrect equipment sequencing can cause damage to the drive.
NOTICE
Damage to Equipment. Do not do a withstand voltage test or use a megohmmeter or megger insulation tester on
the drive. These tests can cause damage to the drive.
NOTICE
Do not operate a drive or connected equipment that has damaged or missing parts. You can cause damage to the
drive and connected equipment.
