Mounting; Choosing A Mounting Location - SMA Sunny Boy 3800U Installation Manual

Section 3:

Mounting

This section provides guidelines to help you select the best mounting location,
suggestions to insure optimum performance, cautions and warnings that you should
follow to avoid injury and/or equipment damage, and step-by-step instructions for
mounting a SB3800U inverter.
WARNING: The SB3800U weighs 85 lb. (38 kg). To avoid in-
jury, be sure to use proper lifting techniques and secure the
help of someone to assist in the unpacking and installation of
the inverter.
Note: Occasionally, the rating label on the SB3800U will need
to be referred to. For this reason, it is required that the inverter
be mounted so that the rating label on the side of the inverter be
visible.

Choosing a Mounting Location

Consider the following guidelines, cautions, and warnings when choosing a mounting
location for the SB3800U:
• Do not install the SB3800U in direct sunlight. External heating from exposure to the
sun may cause excessive internal heating. This can result in derated output power to
protect the internal components from damage.
• Install the SB3800U in a location that maintains an ambient air temperature that is
less than 45°C. To maintain a safe internal component temperature, the SB3800U
may reduce its power output if the ambient air temperature exceeds 45°C. (The
cooler the air temperature, the longer the life expectancy of any power electronics
device.)
• The SB3800U is constructed in a rugged powder coated aluminium enclosure
designed for outdoor installations. However, care should always be taken to
minimize exposure to the elements. It is best to minimize exposure to rain, snow and
ice, etc. Do not install the SB3800U in a location exposed to sources of direct water
spray such as sprinklers or downspouts.
• The inverter should be installed in a location that is inaccessible to children.
• The SB3800U may emit a slight vibrating noise when operating. This vibration is
normal and has no effect on performance, but it may be noticeable if the inverter is
mounted on a wall in a living area, on the outside of a wall that is near a living area,
or on certain types of materials, such as thin wood panelling or sheet metal.
