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. 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.
NOTICE:
Prevent Equipment Damage. Follow cooling fan and circulation fan replacement instructions. Improper fan replacement

fans when performing maintenance to help ensure maximum useful product life.
