1.

 

After mounting the controller, switch the controller to the OFF position. 

 

2.

 

If you are using a remote switch, like a float switch, set dip switch 1 to the correct position for the type of 
switch being used. (“Normally Open” or “Normally Closed”.) If you are not using a remote switch leave 
switch 1 off.  

 
3.

 

Verify all remaining dip switches are off at this time.  
 

4.

 

Connect ground rod conductor to the controller chassis ground block. 

 
5.

 

Connect solar module frame ground conductor to controller chassis ground block. 

 
6.

 

Connect the green pump ground conductor to controller chassis ground block. 

 
7.

 

Connect pump motor leads to the corresponding “Pump Motor” terminals on the controller.  Red to “Red”, 
yellow to “Yellow” and black to “Black”. 

  
8.

 

Verify that the disconnect switch is in the off position.  Connect the DC source supply negative (-), the 
black conductor, to one of the controller terminals labeled “Negative” on the “Solar Array Input”. (NOTE: 
The power should be connected to a disconnect and it should be in the OFF position before connecting 
power to the controller). 

 
9.

 

Connect the DC source supply positive (+), the red conductor, to one of the controller terminals labeled 
“Positive” on the “Solar Array Input”. (NOTE: The power should be connected to a disconnect and it 
should be in the OFF position before connecting power to the controller). 

 
10.

 

Refer to the next section for “Remote Switch” connections and “Adjustment Procedures” for 
configuration, if applicable. 

 
11.

 

At this point, all system components are installed and wired, double check conductor polarities, wire 
termination tightness and controller configuration. With a DC volt meter check the array open circuit 
voltage (Voc) on the array side of the disconnect switch and the module polarity.  Record the Voc for 
future reference.  You may do this on the Before Calling Sun Pumps Worksheet near the end of this 
manual.  Check this voltage reading against the “Voc” range for your specific system in the chart below.  
(Figure 3) 

 
12.

 

After you have verified the voltage and polarity, switch the disconnect switch on - if the polarity is correct 
the first LED light will be on.  

 
13.

 

Turn the “On/Off “switch to the ON position. The system should be operational. If the system does not 
start and turns on any error lights or gives you an error message, proceed to the troubleshooting guide.
