chargers are designed to be wall mountable 

or to sit upright on a table or work surface.  If wall mounting, 
locate the charger within reach of an electrical outlet, and 
away from a corner or other obstructions which may impede 
air flow. Use the back of the charger as a template for the 
location of the mounting screws on the wall. Mount the 
charger securely using drywall screws (purchased separately) 
at least 1” (25.4 mm) long, with a screw head diameter of 
0.28–0.35” (7–9 mm), screwed into wood to an optimal 
depth leaving approximately 7/32” (5.5 mm) of the screw 
exposed. Align the slots on the back of the charger with the 
exposed screws and fully engage them in the slots.
