1. Position the wall mounting bracket at the installation location. If possible, select eye level.
2. Align the wall mounting bracket with a spirit level. The bottom end of the wall mounting bracket

position of the wall mounting bracket (see section 5.3.1 ”Possibilities for Mounting the Wall
Mounting Bracket” (page 30)).
4. Remove mounting bracket and drill the holes at the markings.
5. Insert the screws into the bore holes through the holes in the wall mounting bracket.

• Studs must be present behind the installation points on plasterboard or panels.
Information for the installation
The diameter of the bore holes must correspond to the fastening elements that you use for
mounting the inverter.
Mounting on a concrete wall:
• The hole diameter must be the same as the outer diameter of the screw anchors.
• Insert suitable screw anchors into the bore holes.
Mounting on a wall with wooden studs:
• The hole diameter must correspond to the screw diameter used. The screws are to be
stainless steel. The diameter of the screws must correspond to the diameter of the
holes in the wall mounting bracket. The screws must be long enough to reach a depth
in the wall of up to 1.5 in.
