2.8 Power Connections
Note: Install the sampler on its own 
circuit to ensure a continuous, 
stable source of power.
Use the ac power cords to apply ac power to the controller and 
the refrigerator. 
The sampler controller operates on a 12 V dc which is supplied by a built-in 
ac/dc power converter. The power supply is permanently sealed in the 
compartment located behind the transition plate. An ac line fuse is located on 
the left side of the controller. 
An optional power backup assembly is located on top of the ac power supply. 
The ac power backup is designed to power the pump and controller only. Pull 
the rubber hold-downs up and over the clips at each end of the ac Power 
Backup to hold it in place.
The short, 2-pin cable on the power supply (or battery) connects to the 
controller receptacle labeled 12 V dc.
