General notes
Avoid installing the terminal in environments with the following
characteristics:
•
relative humidity greater than the value specifi ed;
•
strong vibrations or knocks;
•
exposure to water sprays;
•
exposure to aggressive and polluting atmospheres (e.g.: sulphur and
ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or
oxidation;
•
strong magnetic and/or radio frequency interference (for example,
near transmitting antenna);
•
exposure to direct sunlight or the elements in general;
•
large and rapid fl uctuations in the room temperature;
•
environments where explosives or mixes of fl ammable gases are
present;
•
exposure to dust (formation of corrosive patina with possible oxidation
and reduction of insulation).
