8 Installation of the Sunny Central
8.1 Sealing the exhaust air zone
When the inverter is installed in the station, the exhaust air vent of the inverter must be connected to
the exhaust air of the station. The connections between the openings must be sealed tight. This will
ensure that all the warm air exhausted from the inverter is ducted out.
8.2 Fastening the Inverter on the Foundation
Once the inverter has been aligned on the foundation, you can fasten it in place with concrete screw
anchors.
Additional mounting material (not included in the scope of delivery):
☐ 4 suitable concrete screw anchors must be provided.
• Insert the screw anchors through the brackets on the inverter into the foundation. The exact
procedure depends on the type of screw anchors used.
8.3 Disassembling the Panels
The panels are located in the lower section of the connection cabinet.
1. Remove the panel screws using a Torx screwdriver (T30).
2. Carefully remove the front panel of the connection area. First, pull the panel forwards by
80 mm … 100 mm.
3. Detach PE cable from the rear side of the panel.

Damage to the inverter due to overheating.
Non-existent or inadequate sealing between the exhaust air vent of the inverter and the exhaust air
zone of the station may result in overheating of the inverter.
• Make sure that the warm exhaust air from the inverter is ducted out. When selecting the
sealing material make sure it is suited for air temperatures of up to +70°C.
