1.4 Mounting the wall bracket
CAUTION
Hazard when using unsuitable fixing materials!
If unsuitable fixing materials are used, the device could fall and persons in front of the device may be
seriously injured.
› Use only fixing materials that are suitable for the mounting base. The fastening materials supplied are
only suitable for masonry and concrete.
› Only install the device in an upright position.
NOTE
Power reduction due to heat accumulation!
If the recommended minimum clearances are not observed, the device may go into power regulation
mode due to insufficient ventilation and the resulting heat build-up.
› Observe minimum clearances and provide for sufficient heat dissipation.
› All objects on the device housing must be removed during operation.
› Ensure that no foreign bodies prevent heat dissipation following device installation.

diameter.
»The device is connected to the power grid.
1.6.2 Configure DC connection
DANGER
Risk of fatal injury due to electric shock!
Coming into contact with live connections can cause serious injury or death. When there is sunlight
present on the PV generator, there is DC voltage on the open ends of the DC cables.
›Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
›Avoid short circuits.
›Do not connect any PV-strings with a ground fault to the device.
›Ensure that the DC switch is switched off.
