Electrical Shock Hazard
Do not attempt to modify or alter the drive in any way not explained in this manual.
Failure to comply could result in death or serious injury.
Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Do not touch any terminals before the capacitors have fully discharged.
Failure to comply could result in death or serious injury.
Before wiring terminals, disconnect all power to the equipment. The internal capacitor remains charged even after the
power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To
prevent electric shock, wait at least five minutes after all indicators are off and measure the DC bus voltage level to
confirm safe level.
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection, and replacement of parts must be performed only by authorized personnel familiar with
installation, adjustment, and maintenance of AC drives.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Always ground the motor-side grounding terminal.
Improper equipment grounding could result in death or serious injury 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.
Never short the output circuits of the drive.
Do not short the output circuits of the drive. Failure to comply could result in death or serious injury.
When using a PM motor, make sure to block the rotor before performing work on the motor or drive output
circuit.
A PM motor generates electrical power if rotated. If connected to the drive, the drive main circuit will be charged even
if the power supply is off. Touching live parts in the drive or output circuit may result in death or serious injury.
Sudden Movement Hazard
Stay clear of the motor during rotational Auto-Tuning. The motor may start operating suddenly.
During automatic starting of equipment, the machine may start moving suddenly, which could result in death or serious
injury.
System may start unexpectedly upon application of power, resulting in death or serious injury.
Clear all personnel from the drive, motor, and machine area before applying power. Secure covers, couplings, shaft
keys, and machine loads before applying power to the drive.
Fire Hazard
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.
