b. Overvoltage Category II
a local level such as an electrical wall outlet.
c. Pollution Degree 2
reduction of dielectric strength or surface resistivity. Degree 2 refers only to normally
nonconductive pollution. Occasionally, however, expect a temporary conductivity caused by
condensation.
d. Moisture Protection – Normal (IPXO) – IPXO means that no Ingress Protection against
any type of dripping or sprayed water exists. The "X" is a placeholder that identifies
protection against dust, if applicable.
