Installation Procedure


Section Safety
Do not inspect, connect, or disconnect any wiring while the drive is energized.
Failure to comply will cause death or serious injury.
Before servicing, disconnect all power to the equipment and wait for at least the time specified on the warning label.
The internal capacitor remains charged even after the drive is de-energized. The charge indicator LED will extinguish
when the DC bus voltage is below 50 Vdc. When all indicators are OFF, measure for unsafe voltages to confirm the
drive is safe.
Do not operate equipment with covers removed.
Failure to comply could cause death or serious injury.
The diagrams in this section may include options and drives without covers or safety shields to illustrate details.
Reinstall covers and shields before operating the drive and run the drive according to the instructions described in this
manual.
Do not allow unqualified personnel to perform work on the drive or option.
Failure to comply could cause death or serious injury.
Only authorized personnel familiar with installation, adjustment, and maintenance of AC drives and options may
perform work.
Do not remove covers or touch circuit boards while the drive is energized.
Failure to comply could cause death or serious injury.
Do not use damaged wires, stress the wiring, or damage the wire insulation.
Failure to comply could cause death or serious injury.
Tighten all terminal screws to the specified tightening torque.
Loose or overtightened connections could cause erroneous operation and damage to the terminal block or start a fire
and cause death or serious injury.
Observe proper electrostatic discharge (ESD) procedures when handling the option, drive, and circuit boards.
Failure to comply could cause ESD damage to circuitry.
Never connect or disconnect the motor from the drive while the drive is outputting voltage.
Improper equipment sequencing could damage the drive.
Do not connect or operate any equipment with visible damage or missing parts.
Failure to comply could further damage the equipment.
Do not use unshielded wire 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.
