Locate the controller in area protected from direct sun, high temperature, and water. Make sure
there is good ventilation.

3.3.5 Step 5: Secure Controller
Place the controller on the surface and align the mounting holes with the drilled holes in Step
3.3.4. Secure the controller in place using 4, #8 self tapping screws.
