Step 1: Choose mounting location
Locate the MPPT40CC on a vertical surface protected from direct sunlight, high
temperature, and water.
Step 2: Check for Clearance
Place the MPPT40CC in the location where it will be mounted. Verify that there is
sufficient room to run wires and that there is sufficient room above and below the
controller for airflow.
Step 3: Mark Holes
Use a pencil or pen to mark the four (4) mounting hole locations on the mounting
surface.
Step 4: Drill Holes
Remove the controller and drill four sizeable holes in the marked locations.
Step 5: Secure Controller
Place the controller on the surface and align the mounting holes with the drilled
holes in step 4. Secure the controller in place using the mounting screws.
3.3 Wiring
NOTE: A recommended connection order has been provided for
maximum safety during installation.
NOTE: The MPPT40CC is a negative ground controller. Any negative
connection of the solar module, battery or load can be earth grounded.
CAUTION: Don’t connect the loads with surge power exceeding the
ratings of the controller.
CAUTION: For mobile applications, be sure to secure all wiring. Use
cable clamps to prevent cables from swaying when the vehicle is in motion.
Unsecured cables create loose and resistive connections, which may lead
to excessive heating and/or fire.
