4.4 Mounting the Installation TrayAdditional mounting material (not included in the scope of delivery):

• 10 screws with a maximum diameter of 5⁄16 in. (8 mm).• At least 10 washers

1. Position the installation tray between two upright profiles. While doing so, ensure that the installation tray is level with the upright profiles.

2. Mark the position of the holes.3. Drill the holes.

Selecting the installation heightSo that the display of the inverter is at eye-level after mounting, mount the Flush‑Mount Kit with its lower edge about 3 ft. 3 in. (approx. 1 000 mm) above the ground.



4. Secure the installation tray to the upright profiles with at least six screws and washers.

4.5 Attaching the Wall Mounting Bracket

1. Unscrew the three hexagon nuts and three washers from the threaded bolts of the installation tray.

2. Insert the wall mounting bracket into the threaded bolts of the installation tray.

3. Secure the wall mounting bracket with three washers and three hexagon nuts. Tighten the nuts with a torque of (6 Nm).

Tolerance compensationIf the distance between the upright profiles exceeds the width of the installation tray, you can place one or more washers between the upright profiles and the installation tray. This prevents the installation tray from moving.

Wall mounting bracket of the inverterThe wall mounting bracket is included in the inverter's scope of delivery.



4.6 Mounting the Inverter

Risk of crushing due to falling individual parts of the inverter and during installation. • The weight of the individual parts must be a maximum of 40 lbs. (18 kg) during mounting.• Always use both hands to lift individual parts of the inverter.

Observe the installation guide of the inverter.• Carry out all mounting and installation work on the inverter in accordance with the installation

guide of the inverter.
