Installation Guide
4.3.2 Mounting the wall mounting bracket
1. Position the wall mounting bracket against the wall where you intend to mount the Sunny Boy.
(Try to mount the Sunny Boy so that the display is approximately at eye-level.) Place a level on
the top edge of the bracket, and adjust the position of the bracket until it is level. The enclosure
bottom of the inverter will be located approximately 9
3
⁄
4
in. (240 mm) underneath the lower
end of the wall mounting bracket.
2. Using the wall mounting bracket as a template, mark the wall through the holes in the horizontal
or vertical portion of the bracket (see section 4.3.1 ”Possibilities for mounting the wall mounting
bracket” (page 23)). Set the bracket aside temporarily.
3. Ensure that the material behind the markings for the drill holes is capable of bearing load.
4. Drill holes at the marks you made on the wall.
5. Insert wall anchors into the drill holes.
DO NOT use molly or toggle bolts to mount the Sunny Boy to sheet rock or panelling.
DANGER
Drilling into live cables.
Death or serious injury due to electric shock.
• Before drilling the holes, check whether electricity cables run through the walls at the
desired mounting location. If cables run through the walls at the desired mounting
location, then select a different mounting location.
CAUTION
Danger of crushing due to the Sunny Boy falling.
Crushing of body parts.
• If mounting onto a wall, ensure that the wall can carry the weight of the Sunny Boy.
• If mounting onto a wooden wall with studs, ensure that the wall mounting bracket is
firmly connected with all studs and the stud can carry the weight of the Sunny Boy.
Tip for installing
The diameter of the holes you drill must match the hardware you are using to mount the
Sunny Boy.
For example, if you are mounting the Sunny Boy to a concrete wall, the hole diameter must
be approximately the same as the outside diameter of the concrete anchors you intend to
use. If you are mounting the Sunny Boy on a wall that has wooden studs inside it, the hole
diameter must be the correct size for the lag screws you intend to use to mount the bracket.
It is recommended that the lag screws be made of stainless steel, and the diameter of the
screws closely match the diameter of the holes in the wall mounting bracket. Make sure
that the screws are long enough to penetrate the wall to a depth of 1
1
⁄
2
in. (38 mm).
