Mounting Details 

The AMG unit is supplied with a clip-on mounting bracket which should be attached to a panel or wall 
using 2 off 4.0mm screws, see diagram on page 1 for dimensions. The unit is clipped into the 
mounting bracket, and is then held firmly in position. 
 

 

Removal / replacement from / to the Case 

Note: - The AMG unit PCB's are static sensitive. Handle with proper care and use normal electrostatic 
discharge (ESD) procedures. Use properly grounded protection (for example, wrist straps) when 
handling the PCB.  
 
To remove units from the case to access the data expansion boards and the daughter boards, remove 
the 2 or 4 fixing screws on the rear panel and slide the PCB's out of the case.  
Ensure that the fibres do not snag or get trapped.  
 
To replace the PCB's into the case, slide the PCB's gently into the case aligning the boards with the 
appropriate slots. Ensure that the fibre do not snag or get trapped.
