What Do I Need for Installation?

 

If you already have your system set up and are ready to drop in your batteries, you will need a torque wrench that is 
able to fit to and properly torque your 5/16” finishing hardware. This is REQUIRED to make sure that you torque to the 
specification of 9 to 11 ft-lb, otherwise you may cause system failures and damage. 

Connecting Load Specified Cables to the Batteries

 

1. Identify the positive and negative terminals. These are labeled and color-coded 

red

for positive (+)

black for negative (–)

.

2. Determine which finishing hardware set you will use. Verify that your bolt can fully seat into the nylok insert of the 

nut. If multiple lugs are used, longer bolts may be required for the bolt to fully seat into the nylok insert of the nut.

3. Connect your cable lugs to your battery terminal with the previously identified finishing hardware set. Make sure to 

connect your positive load specified cable lug to the positive terminal and the negative load specified cable lug to 

the negative terminal. The proper order to connect to your terminal with a finishing kit is shown in Fig. 1.

Figure 1: 

Proper order of hardware to connect cables. When going from left to right in the diagram the correct order is: 

bolt, washer, lug, terminal, washer, and nut. If multiple lugs are used, they should be on the same side of the terminal. 

4. When connecting to your battery terminals, 

DO NOT 

finger tighten. Use a torque wrench to torque your hardware

to the specification of 9 to 11 ft-lbs. Failure to adequately secure connections can result in severe damage and will
void your warranty. Fig. 2 below demonstrates proper and improper connections.
