Verify motor wiring bare wire ends do not contact the drive chassis or enclosure when wiring drive terminals U/
T1, V/T2, W/T3.
Failure to comply may result in serious injury or death due to electrical shock.
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 use the 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.
Before servicing, disconnect all power to the equipment and lock out the power source.
Failure to comply may result in injury from electrical shock. Wait at least five minutes after all indicators are OFF and
measure the DC bus voltage level and main circuit terminals to confirm the circuit is safe before wiring.
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 in drive installation, repair or maintenance.
Failure to comply could result in death or serious injury by fire. Attach the drive or braking resistors to metal or other
noncombustible material.
CAUTION
Burn Hazard
Do not touch a hot drive heatsink. Failure to comply could result in minor or moderate injury.
Shut off the power to the drive when replacing the cooling fan. To prevent burns, wait at least 15 minutes and make sure
heatsink has cooled down.
NOTICE
Equipment Hazard
Never connect or disconnect the motor from the drive while the drive is outputting voltage. Improper
sequencing of output motor circuits could result in damage to the drive.
Do not connect electromagnetic switches or magnetic contactors to the output motor circuits without proper
sequencing. Do not open the main circuit between the drive and the motor while the PM motor is rotating.
