Step 1: Wiring

 

The recommended connection order has been provided as Figure3-2 

indicated. Be sure the positive and negative polarity is correct and all 

terminals are tightened. 

Figure 3-2    System wiring review

 

Step 2: Confirm power on

 

When battery power is applied and the controller starts up, the battery 

LED indicator will be green. If the controller doesn't start up, or the 

battery status LED error exists, please refer to section 5 for 

troubleshooting.
