NOTE: Working gloves are strongly recommended when performing installation steps.
Ensure the mounting surface is strong enough to handle 3 times the total weight of all the components. Add plywood
or other reinforcing material as necessary to strengthen the surface.
Attach the wall bracket. Center the mounting holes on the wall studs. Use all 6 mounting screws to secure the
bracket.
Lift the inverter high enough that the inverter bracket is above the wall bracket.
Lower the inverter so that the top of the back plane flange slips into the wall bracket. Ensure the unit is centered on
the wall bracket.
Install the mounting screws. See illustration below for preferred locations for maximum mounting strength.
