Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized drive. Before servicing, disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.

| Warning |
|
Electrical Shock Hazard
Do not operate the drive when covers are missing. Replace covers and shields before you operate the drive. Use the drive only as specified by the instructions.
Some figures in this section include drives without covers or safety shields to more clearly show the inside of the drive. If covers or safety shields are missing from the drive, 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 remove covers or touch circuit boards while the drive is energized.
If you touch the internal components of an energized drive, it can cause serious injury or death.
|
| 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
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 |
|
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 |
|
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 |
|
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 |
|
Crush Hazard
Wear eye protection when you do work on the drive.
If you do not use correct safety equipment, it can cause serious injury or death.
|
| Warning |
|
Electrical Shock Hazard
After the drive blows a fuse or trips an ELCB, 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.

| 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
Before you connect a dynamic braking option to the drive, make sure that qualified personnel read and obey the Braking Unit and Braking Resistor Unit Installation Manual (TOBPC72060001).
If you do not read and obey the manual or if personnel are not qualified, it can cause damage to the drive and braking circuit.
|
| Notice |
|
Make sure that all connections are correct after you install the drive and connect peripheral devices.
Incorrect connections can cause damage to the drive.
|
Note:
Do not use unshielded cable for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive. Unshielded wire can cause electrical interference and unsatisfactory system performance.
