Multimeter

Mounting

Step 1: Choose Mounting Location

Locate the SunSaver on a vertical surface within 10 feet (3 m) of the battery bank that is protected from direct sun, high temperatures, and water.

Step 2: Check for Clearance and Ventilation

Place the SunSaver in the location where it will be mounted.
Verify that there is sufficient room to run wires and that
there is ample 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 3/32” (2.5 mm) 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 (included).
