Replace a Fan (Procedure B)

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
useful product life. Improper fan replacement could cause damage the drive.
