16 SB33_38-IEN111851 Installation Guide
• Install vertically or tilted backwards at a maximum angle of 45°.
• The connection area must point downwards.
• Never mount the device with a forward tilt.
• Never install the device with a sideways tilt.
• Do not mount horizontally.
• Install at eye level in order to allow operation conditions 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 optimal operation.
• Do not expose the inverter to direct sunlight to avoid power reduction due to excessive heating.
• 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
sufficient space for removing the Electronic Solar
Switch.
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 ventilation to ensure sufficient cooling of the inverters
