Section Safety
Power to the drive must be shut off when installing this option card.
Even though the power has been shut off, voltage still remains in the drive's DC bus. Wait before removing the front cover once the
drive has been turned off.
The CHARGE light on the drive will go out after voltage in the DC bus drops below 50 V, at which point it is safe to remove the
front cover.
Due to the risk of electric shock, be sure that all LEDs have gone out and that the DC bus voltage has reached a safe level prior to
performing any work on the drive.
Do not remove the front cover of the drive while the power is on.
Failure to comply could result in death or serious injury.
The diagrams in this section may include option cards 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.

Failure to comply could result in death or serious injury.
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 card, 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.
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 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.
Properly connect all pins and connectors.
Failure to comply may prevent proper operation and possibly damage equipment.
Check wiring to ensure that all connections are correct after installing the option card and connecting any other devices.
Failure to comply may result in damage to the option card.
