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.
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.
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.
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.
Do not connect the AC power line to the output motor 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. could result in death or serious injury by fire as a result of drive damage from line
voltage application to output terminals.
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 modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
