Definitions:
Enclosure Category 2: Enclosures where no pressure difference relative to the
surrounding air is present.
Installation Category II (Overvoltage Category II) or CAT II: Equipment is intended
for connection to the fixed installation of a building. The power supply to the electronic
equipment is separated from other circuits, usually by a dedicated transformer for the
mains power supply.
Measurement/Installation Category III (Overvoltage Category III) or CAT III:
Distribution Level, fixed installation, with smaller transient overvoltages than those at
the primary supply level, overhead lines, cable systems, etc.
Pollution: Any degree of foreign matter, solid, liquid, or gaseous that can result in a
reduction of electric strength or surface resistivity of the insulation.
Pollution Degree 2: Only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation is to be expected.
