MODULE FITTING INSTRUCTIONS
Beware of ESD! Observe anti-static handling precautions—avoid touching the electronic devices on
the circuit board, ensure any static build up is discharged to earth before handling the module.
This can be achieved by ensuring the console is connected to the psu and the psu is plugged in to a
mains outlet but switched OFF, then touching a metal part of the console panel such as a screw head.
Remove 4 x screws
Remove the blanking panel at the
rear of the console by removing
the 4 screws.
Locate the module circuit board
in the plastic guide slots within
the housing.
lide the module into the housing
and push firmly to insert the
module connectors into the con-
sole connector sockets.
Re-fit the 4 fixing screws to the
module panel.
Push
To remove the module for any reason, the easiest way is to unscrew and remove the fixing screws at each end of the panel
then use the D ub cable connectors to gently pull out the module. A small side to side rocking action will help to displace
the circuit board connectors from the internal mother-board.
