Do not use US40a in the place where corrosive gases exist.
Make sure not to locate or use US40a in the place where corrosive gases (sodium
chloride, sulfur dioxide, hydrogen sulfide, nitrogen dioxide, chlorine, ammonia, ozone,
etc.) exist.
Also, do not set it in the environment where the air (or dust) includes components
accelerating corrosion (ex. sulfur, etc.) or conductive metals. There is a risk of a fire
due to corrosion and shorts of an internal printed board. Ask your service
representative for a place appropriate to US40a if you have any questions about the
environment.
