• Mount vertically or tilted backwards at a maximum angle of 45°.
• The connection area must point downward.
• Never mount the device with a forward tilt.
• Never mount the device with a sideways tilt.
• Do not mount horizontally.
• Install at eye level in order to allow operation states to be read at all times.
• The inverter must be easy to remove from the mounting location at any time.
• The ambient temperature should be below 40°C to ensure optimum operation.
• Do not expose the inverter to direct solar irradiation as this can cause excessive heating and
thus power reduction.
• In living areas, do not mount the unit on plasterboard walls or similar to avoid audible vibrations.
The inverter can make noises when in use which may be perceived as a nuisance in a living
area.
• Observe the minimum clearances to walls, other
inverters, or objects as shown in the diagram in
order to ensure sufficient heat dissipation and,
if applicable, sufficient space for removing the
Electronic Solar Switch if included.
Multiple inverters installed in areas with high ambient temperatures
If necessary, increase the clearances between the individual inverters. In addition, make
sure there is enough fresh-air supply to ensure sufficient cooling of the inverters.
