There are two different methods for electrical connection between the sensor and the pH controller; either direct 
or through a junction box. 

 

 

1.  Use a watertight cord grip to insert the sensor cable into the Alpha pH2000D Controller.  Conduit holes 

are found on the bottom of the Alpha pH2000D controller for this purpose. 

2.  Connect the sensor wires to the Alpha pH2000D controller as outlined in the controller manual. 

 

 

1.  Use a watertight cord grip to insert the sensor cable and the interconnect cable into the junction box 

that has a terminal strip designed to make the proper connections. 

2.  Connect both the sensor cable wires and the interconnect wires to the terminal strip. 
3.  Use a watertight cord grip to insert the sensor cable into the Alpha pH2000D Controller.  

Conduit holes are found on the bottom of the Alpha pH2000D controller for this purpose. 

4.  Connect the sensor wires to the Alpha pH2000D controller as outlined in the controller manual. 

 

Be sure that the wire colors of the sensor cable match those of the interconnect cable on 
either side of the terminal strip. 

 

 

 

Route the interconnect cable through metal conduit to minimize electrical noise that may 
interfere with the sensor signal.
