6.2.2 Detaching the Module Casing

1. Remove the two T8 screws mounting the D25 

connector shield.

2. Detach the connector shield.
3. Remove the two T8 screws to detach the module 

casing.

4. Push the latch and pull the module casing.
NOTE: When reassembling ensure that the module 
casing does not damage the conductive sealings on 
the front chassis unit.
