4 Mounting
4.1 Selecting the Mounting Location
Observe the following conditions during mounting:
• The mounting location and method must be suitable for the weight and dimensions of the
Sunny Island.
• Mount on a solid support surface.
• The mounting location must be accessible at all times.
• The ambient temperature must be between − 13°F ( − 25°C) and +140°F (+60°C).
• Do not expose the Sunny Island to direct solar irradiation, so as to avoid power reduction due
to excessive heating.
Danger to life if installed in improper locations
Death or serious burns. Despite careful construction, electrical devices can cause fires.
• Do not mount the Sunny Island on flammable construction materials.
• Do not mount the Sunny Island near highly flammable materials.
• Do not mount the Sunny Island in potentially explosive areas.
Risk of injury through contact with hot enclosure parts during operation
Burns to the body.
• Mount the inverter in such a way that the enclosure cannot be touched inadvertently.
Risk of injury due to the Sunny Island falling during transport or mounting
Physical injury (fractures or crushing) and damage to the Sunny Island.
• Take the weight of the Sunny Island of 139 lb (63 kg) into account.
• Use the recessed grips or steel bars for transporting and mounting.
Overheating of the Sunny Island due to insufficient clearance to other Sunny Island
inverters in areas with high ambient temperatures
If several inverters have been installed in areas with high ambient temperatures, the
independent cooling of individual inverters needs to be guaranteed.
If necessary, increase the clearances between the individual inverters and make sure there is
enough fresh-air supply to ensure optimum operation of the inverters.
The Sunny Island switches itself off automatically in the event of overtemperature.
