IM CA150E
Pollution Degree
The pollution degree of the CA150 in the operating environment is 2.
Pollution Degree applies to the degree of adhesion of a solid, liquid,
or gas which deteriorates withstand voltage or surface resistivity.
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 ± 5°C
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.
Storage location
• We recommend you store the CA150 in an environment with a temperature
between 0 and 50°C and a relative humidity between 5 to 85% RH.
• When storing the CA150, avoid a location that is:
• Outdoors,
• exposed to direct sunlight,
• exposed to water or other liquids,
• 60°C or higher,
• 90% RH or higher,
• close to a heat source,
• exposed to severe vibrations,
• exposed to corrosive or explosive gas, or
• exposed to excessive amount of soot, dust, salt, and iron.
