1. Locate the refrigerator vent on the roof of the RV. Remove vent cover to gain access to the duct opening.
 

2. Drill a hole through the side of the vent (5/8” hole).
 

3. Remove any sharp edges from the hole.
 

4. Insert a rubber grommet (not included) into the hole.
 

5. Insert the MC4 Positive and Negative Extension Cables through the hole and carefully route it to the GP-RVC-30-MPPT Solar Charge Controller. Be certain to leave enough slack to allow cable routing from module to vent along desired path.
 

6. Use cable clamps with the #6 self-tapping screw and/or tie wraps every few feet along RV roof and interior route to the GP-RVC30-MPPT Solar Charge Controller.
 

7. Ensure all penetrations into the RV roof are watertight. Use an appropriate sealant as recommended by your RV Dealer to seal holes wherever necessary.
 

8. Replace vent cover.
