Class of Equipment I
1 Installation category (overvoltage category) defines the level of transient overvoltage
that the instrument is designed to withstand safely. It depends on the nature of the
electricity supply and its overvoltage protection means. For example, in CAT II which is
the category used for instruments in installations supplied from a supply comparable to
public mains such as hospital and research laboratories and most industrial laboratories,
the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V
supply.
2 Pollution Degree describes the amount of conductive pollution present in the operating
environment. Pollution Degree 2 assumes that normally only non-conductive pollution
such as dust occurs with the exception of occasional conductivity caused by condensation.
