Power Supply Unit 

 

The General Assembly 

 

 

NOTE: The diagram above shows a V3 PSU. Earlier models differ slightly. 

 

The  power  supply  is  normally  supplied  disassembled  to  make  first  fix  easier.  If  the  panel  is  already 
assembled it must be disassembled in order to fix the backbox to the wall. 

 

If  the  power  supply  needs  to  be  disassembled  in  order  to  fix  the  box  to  the  wall  see  “Power  Supply 
Disassembly”.
