Fan Replacement (Procedure H)

DANGER! Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor
stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below 50
Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the drive is safe. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
CAUTION! Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum of 15 minutes, then make
sure that the heatsink is cool before you replace the cooling fans. If you touch a hot drive heatsink, it can burn you.
NOTICE: Use the instructions in this manual to replace the cooling fans. When you do maintenance on the fans, replace all the fans
to increase product life. If you install the fans incorrectly, it can cause damage to the drive.
