Section Safety
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Disconnect all power to the drive, wait at least five minutes after all indicators are off, measure the DC bus
voltage to confirm safe level, and check for unsafe voltages before servicing to prevent electric shock. The
internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will
extinguish when the DC bus voltage is below 50 Vdc.
Do not remove option board cover while the power is on.
Failure to comply could result in death or serious injury.
The diagrams in this section may include option units and drives without covers or safety shields to show
details. Be sure to reinstall covers or shields before operating any devices. The option board should be used
according to the instructions described in this manual.

Do not use damaged wires, place excessive stress on wiring, or damage the wire insulation.
Failure to comply could result in death or serious injury.
Observe proper electrostatic discharge procedures (ESD) when handling the option unit, drive, and
circuit boards.
Failure to comply may result in ESD damage to circuitry.
Never shut the power off while the drive is outputting voltage.
Failure to comply may cause the application to operate incorrectly or damage the drive.
Do not operate damaged equipment.
Failure to comply may cause further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance.
