WARNING! Electrical Shock Hazard. While the drive is ON, never attempt to change any wiring, disconnect any option cards or

connectors, or replace the cooling fan. Before performing any repairs, shut OFF the power supply to the drive and verify that

there is no residual voltage in the unit. Failure to do so may result in serious electric shock.

WARNING! Electrical Shock Hazard. Only authorized persons qualified in electrical work should perform installation, wiring,

maintenance, inspections, parts replacement, and repairs. Failure to comply may cause electrical shock.

WARNING! Electrical Shock Hazard. Do not perform inspections or wiring while the drive is energized. De-energize all devices

before carrying out any wiring or repair operations. Voltage will remain within the capacitors inside the drive even after the

power has been switched off. The Charge LED is extinguished once the DC bus voltage goes below 50 V DC. To prevent

electric shock, always wait for at least the amount of time indicated on the warning labels and confirm that all indicators are

OFF. Then, remove the front cover and terminal cover, measure the input power supply voltage and the DC bus voltage, and

make sure that the voltages have been lowered to safe levels. Failure to comply may result in death or serious injury.

NOTICE: Observe proper electrostatic discharge (ESD) procedures when handling the drive and circuit boards. Failure to

comply could cause ESD damage to the drive circuitry.
