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.

CAUTION! Preventing Burns. Do not touch the heatsink of the drive as it is very hot. To replace cooling fans, de-energize the

drive and wait at least 15 minutes. Make sure the heatsink has sufficiently cooled before proceeding to replace a fan. Touching

the device may result in burns in certain circumstances.

NOTICE: Follow cooling fan replacement instructions. Replace all fans when performing maintenance to help ensure maximum
