7.1 Section Safety
W ARNING
Fire Hazard
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
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.
Do not use improper combustible materials.
Failure to comply could result in death or serious injury by fire.
Attach the drive to metal or other noncombustible material.
NOTICE
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Follow cooling fan replacement instructions. The cooling fan cannot operate properly when it is installed
incorrectly and could seriously damage the drive.
Follow the instructions in this manual to replace the cooling fan, making sure that the label is on top before inserting
the cooling fan into the drive. To ensure maximum useful product life, replace both cooling fans when performing
maintenance.
Never connect or disconnect the motor from the drive while the drive is outputting voltage.
Improper equipment sequencing could result in damage to the drive.
Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance. Use shielded, twisted-pair
wires and ground the shield to the ground terminal of the drive.
Do not allow unqualified personnel to use the product.
Failure to comply could result in damage to the drive or braking circuit.
Maintenance, inspection, and replacement of parts must be performed only by authorized personnel familiar with
installation, adjustment and maintenance of AC drives.
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
YASKAWA is not responsible for any modification of the product made by the user. This product must not be
modified.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other
devices.
Failure to comply could result in damage to the drive.
Comply with proper wiring practices.
The motor may run in reverse if the phase order is backward.
Connect motor input terminals U, V and W to drive output terminals U/T1,V/T2, and W/T3. The phase order for the
7
drive and motor should match.
Frequently switching the drive power supply to stop and start the motor can damage the drive.
To get the full performance life out of the electrolytic capacitors and circuit relays, refrain from switching the drive
power supply off and on more than once every 30 minutes. Frequent use can damage the drive. Use the drive to stop
and start the motor.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
