Safety Messages

Do not connect or disconnect wiring while the power for the main circuit and controls is on.
Failure to comply could result in death or serious injury.
Do not touch the input and output terminals directly with your hands and do not bring the input and output wires into
contact with the drive case or metal parts. In addition, do not short circuit the output wires.
Failure to comply could result in death, serious injury, or ground fault.
After an emergency stop circuit has been wired, check to make sure that it is operating properly. Emergency stop
circuits are needed to safely and quickly stop the operation of the drive.
Operating a drive with an emergency stop circuit whose operation has not been checked could result in death or serious
injury.
Confirm the drive I/O signals and external sequence before starting the test run.
Failure to comply may result in death or serious injury.
Do not supply power to the main circuit while the panel doors are open.
Failure to comply could result in death or serious injury.
The diagrams in this section may show the drive without covers or safety shields to show details. Be sure to reinstall
covers or shields before operating the drive and run the drive according to the instructions described in this manual.
Always ground the motor-side ground terminal.
Improper equipment grounding could result in death, serious injury, or fire by contacting the motor case.
Do not perform work on the drive while wearing loose clothing, jewelry, or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing and wear eye protection before beginning
work on the drive.
Do not allow unqualified personnel to perform work on the drive.
Failure to comply could result in death or serious injury.
The drive should be installed, wired, repaired, inspected, and have its parts replaced, by someone with a thorough
knowledge of drive installation, adjustment and repair.
Turn off the power for the main circuit and controls to all devices before connecting the drive's terminals.
Even when the power supply of the medium-voltage main circuit to the drive is shut off, it takes some time for the
internal capacitors to discharge. Wait until the CHARGE LED goes off before starting inspection. While an electric
charge remains in the capacitor, the surface and inside of the Power Cell will carry a high voltage, so there will be a
risk of death or serious injury.
Use a ground wire of a gauge that complies with the technical standards for electrical equipment in the country where
the drive is being used. Keep the wiring as short as possible.
Improper equipment grounding could cause leakage current to flow to the drive. If so, the potential of the drive's
ground terminals becomes unstable at some distance from the grounding point, resulting in death or serious injury.
