1 Safety Instructions and General Warnings
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.
Do not connect the AC power line to the output terminals of the drive.
Failure to comply could result in death or serious injury by fire as a result of drive damage from line voltage
application to output terminals.
• Do not connect AC line power to output terminals U, V, and W.
• Make sure that the power supply lines are connected to main circuit input terminals R/L1, S/L2, T/L3 (or R/L1 and S/
L2 for single-phase power).
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.
Use a dedicated lifter when transporting the drive by a lifter.
Improper lifter may cause the drive to drop, resulting in serious injury.
Only allow qualified personnel to operate a crane or hoist to transport the drive.
Failure to comply could result in death or serious injury from falling equipment.
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
Do not touch the heatsink or braking resistor hardware until a powered-down cooling period has elapsed.
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.
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 perform a withstand voltage test on any part of the unit.
Failure to comply could result in damage to the sensitive devices within the drive. Use power off resistance checks to
determine shortcircuits.
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.
