Step 4: Install the Module
Reversing the orientation of the fan assembly
The U1084A Digitizers are supplied with a fan unit. This fan unit is required for
operation, and should not be removed.
The cooling fan assembly of the U1084A takes up 2 PC slots at the rear. It has been
designed to be mounted in either a left or right orientation to allow adaptation to
different PC or chassis hardware, or also to allow two U1084A modules to be
positioned side-by-side.
To change the orientation please use the following procedure:
1. Remove the 2 screws (top & bottom) nearest to the front of the fan unit, and
remove the 2 retaining clips (shown pale red in the diagram).
2. Slide the fan unit approximately 15mm to the rear unit it clears the circuit board,
and rotate it by 180°.
3. Slide the fan unit back towards the module until it is fully seated into the loc-
ating slots.
4. Replace the 2 retaining clips, and refit and tighten the 2 screws (0.5 Nm torque).
