Backplane DC Power Connection 

 

Make sure you connect the control system to an external 12 VDC power source. 
 
The control system typically uses +12 to +14 VDC and will operate down to10 VDC with 
no problems.  The external DC power is supplied through a 2 pin connector mounted on 
the back of the control system.   
 

    

   

 

 
The alignment tab is on the top of the connector.  As you look at the back of the 
backplane, the left pin is +12 VDC in and the right pin is ground. 
Make sure the connector is plugged in correctly.  The control system is internally fused 
on the power supply board just in case something gets shorted out.  The fuse value 
should be 3 amps.
