1.
Remove and lock-out all incoming power to the drive. Remove/open the
drive cover.
2.
Using figure 1, locate the fan and attached wires. Note wire routing.
3.
Remove the fan connector from the chassis. Cut the wire approximately
25.4 mm (1 in.) from the connector. Discard wire and connector.
4.
Remove the four screws securing the fan guard to the heatsink. Set the
fan guard and screws aside. Remove and discard the fan and wires.

ATTENTION:
This drive contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing
or repairing this assembly. Component damage may result
if ESD control procedures are not followed. If you are not
familiar with static control procedures, reference A-B
publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection
handbook.
!
ATTENTION:
To avoid a shock hazard, assure that all
power to the drive has been removed before proceeding. In
addition, verify that the DC bus has discharged by
measuring across the “+DC” and “–DC” terminals of TB1
with a voltmeter. The voltage should be 0.0VDC.
