Chapter 3.4 Opereting Environment Internal Wiring Distribution Board Entrance Cable CAT. IV CAT. III CAT. II T CAT. I 3 Outlet Equipment Pollution Degree Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand voltage or surface resistivity. The pollution degree of the CA150 in the operating environment is 2. Pollution Degree 2 applies to normal indoor atmospheres. Normally, only non-conductive pollution is emitted. However, a temporary electrical conduction may occur depending on the concentration. Note • For accurate source and measurement, operate the CA150 in the 23 ± 5C temperature range and 55 ± 10% RH. • Condensation may occur if the CA150 is moved to another place where the ambient temperature and humidity are higher, or if the temperature changes rapidly. If this happens, let the CA150 adjust to the new environment for at least two hours before using it. Strage Location • We recommend you store the CA150 in an environment with a temperature between 0 and 50C and a relative humidity between 5 to 85% RH. • When storing the CA150, avoid a location that is: • exposed to direct sunlight, • 60C or higher, • 90% RH or higher, • close to a heat source, • exposed to servere vibrations, • exposed to corrosive or explosive gas, • exposed to excessive amount of soot, dust, salt, and iron, or • exposed to water, oil, or chemicals.
