Location: Indoor, no direct sunlight, dust free, almost non-conductive
pollution (note below)
Relative Humidity: < 80%
Altitude: < 2,000m
Temperature: 0 to 40°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and
their requirements as follows. The IPS X303 series falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or gaseous
(ionized gases), that may produce a reduction of dielectric strength or
surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive pollution
occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by
condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment is
normally protected against exposure to direct sunlight, precipitation,
and full wind pressure, but neither temperature nor humidity is
controlled.
