1. Locate the positive battery cable from the GP-RVC-30-MPPT.
 

2. Plan where you can safely and easily access the fuse holder & fuse.
 

3. Cut the battery positive cable from the GP-RVC-30-MPPT to the planned lengths.
 

4. Strip the fuse holder cable and positive cable from GP-RVC-30-MPPT as shown in Fig 4-F.

5. Thread the red heat-shrink onto the fuse holder cable.
 

6. Insert the fuse holder and GP-RVC-30-MPPT stripped cable ends into the butt splice as shown in Fig 4-G.
 

7. Crimp the butt splice fully - test the connection by gently pulling on both cables.
 

8. Thread the heat-shrink over the butt splice as shown in Fig 4-H.
 

9. Use the heat gun to shrink the heat shrink over the butt splice as shown in Fig 4-I.
 

10. Repeat the process for the other fuse holder cable & battery bank connection.

11. Do not install the 30A Fuse at this stage.
