7.1 Section Safety
A WARNING
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 o f parts must be performed only by authorized personnel familiar with
installation, adjustment and maintenance of AC drives.
Switch off and lock power supply and lock the switch before wiring terminals.
Failure to comply could result in serious injury or death.
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 o f 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 o f the drive matches the voltage o f 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.
A 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.
Equipment Hazard
Never connect or disconnect the m otor from the drive while the drive is outputting voltage. Im proper
sequencing of output m otor 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.
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.
Do not connect or disconnect the m otor from the drive while the drive is outputting voltage.
Improper equipment sequencing could result in damage to the drive.
