Mounting Method
The Sunny Island 4248U was designed to be wall-mounted in a vertical position. Drywall, or
“wallboard”, is not strong enough to support the weight of the Sunny Island 4248U by itself.
Do not attempt to install the inverter on wallboard without additional support. The inverter can
be mounted on a single wall stud provided that three 1/4 inch lag bolts with washers are used
and provided that the lag screws are long enough to penetrate the stud to a depth of 1 1/2
inches. For additional support, the Sunny Island 4248U may be mounted to 2 x 4 braces, Uni-
Strut or a sheet of plywood that is secured to the building support structure.
Clearances
Air is drawn into the bottom of the inverter and exits through the sides near the top of the
enclosure. To maintain proper air flow, a distance of 6 inches must be maintained on the sides
of the inverter and a distance of 4 inches should be maintained on top of the inverter. All wire
terminations will be made through the bottom of the enclosure, therefore a minimum of 3 feet
of clearance should be maintained below the inverter. For best viewing of the LCD display,
mount the inverter so that the display will be near eye-level. (To help accomplish this, position
the mounting bracket so that the top edge is approximately 8” above eye-level.)
