The main cooling fan is located at the top of the module. The replacement of the main
cooling fan requires that the module is pulled outwards far enough to create room above
the module.
1.
Stop the drive and do the steps in section Electrical safety precautions (page 57) before
you start the work.
2. Remove the air baffles shown:
• Upper-row module: (2a) above the module
• Lower-row module: (2b) above the module.
3. Disconnect all cabling from the module. Move the cables aside.
4. Remove the four mounting nuts and screws of the module (two at the top edge, two at
the bottom edge).
5. Pull the module carefully outwards along its rails until the fan at the top is accessible.
WARNING!
Do not pull the module out any further than what is required to change the fan
(unless you intend to remove the module completely). The rails have no stops
to prevent the module from sliding all the way out.
6. Lift the fan mounting plate by the front edge.
7. Unplug the power supply wires.
8. Lift out the fan assembly.
Install the new fan assembly and insert the module in reverse order to the above. Make
sure that the fan blows upwards.
