The Pollution Degree indicates the level of pollution that can exist in the ambient environment.
Pollution degree 1:
No pollution or only dry, non-conductive pollution occurs. The pollution has no
influence.
Pollution degree 2:
Only non-conductive pollution occurs except that occasionally a temporary
conductivity caused by condensation is to be expected.
Pollution degree 3:
Conductive pollution occurs, or dry, non-conductive pollution occurs which
becomes conductive due to condensation which is to be expected.
Pollution degree 4:
The pollution generates persistent conductivity caused by conductive dust or by
rain or snow.

The Overvoltage Category (Installation Category) indicates how much overvoltage (impulse voltage)
from an AC power supply an electrical device can withstand. Overvoltage Category II (CAT II) is suitable
for devices powered by wire from the switchboard of a building.
*
3
The Measurement Category categorizes a testing or measurement circuit according to the type of main
power circuit intended to be connected for testing or measurement, and differs according to the modules
installed to this product. Use the product within the Measurement Category that meets the module
specifications.
CAT II:
Applies to testing and measurement circuits directly connected to the point of use
(power outlet or similar location) of a low voltage main power supply system.
CAT III:
Applies to testing and measurement circuits connected to the switchboard of the low
voltage main power supply system in a building.
CAT IV:
Applies to testing and measurement circuits connected to the source of the low
voltage main power supply system in a building.
No category (O): Applies to circuits not directly connected to a main power supply.
