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).
