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. After shutting off the power, wait for at least the amount of time specified on the drive before touching
any components.
CAUTION! Burn Hazard. Do not touch a hot drive heatsink and filter cases. 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 and
the filter cases have cooled down.
NOTICE: Prevent Equipment Damage. Follow cooling fan and circulation fan replacement instructions. Improper fan replacement
could result in damage to equipment. When installing the replacement fan into the drive, make sure the fan is facing upwards. To
ensure maximum useful product life, replace all fans when performing maintenance.
