Cooling Fan Replacement
The cooling fan is installed on the top of the drive. The cooling fan can easily be replaced without tools or removal of the
drive or enclosure parts.
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply can result in serious
personal injury. Before servicing the drive, disconnect all power to the equipment. The internal capacitor remains charged even after
the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric
shock, wait at least five minutes after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
CAUTION! Burn Hazard. Do not touch a hot drive heatsink. Failure to comply could result in minor or moderate injury. Shut off the power
to the drive when replacing the cooling fan. To prevent burns, wait at least 15 minutes and ensure the heatsink has cooled down.
